Dublin, September 22, 2026 – DIDWW, a fully licensed global telecom operator connecting human and AI communications across 90+ countries, has taken home two top honors at the Antonio Meucci Global Telco Awards 2026. DIDWW was named winner of the Excellence Award for Best Europe Provider and the Honors Award for Best Voice Provider, a double win that reflects the company's continued growth across its licensed footprint and its focus on reliable, high-quality voice services.

Now in its fourth year, the Antonio Meucci Global Telco Awards recognize achievements across nearly 30 categories spanning voice, messaging, IoT, and other areas of the telecom industry. In 2026, more than 100 telecom professionals served on the judging committees, bringing expertise from across the global telecommunications sector. Entries were evaluated through a two-phase process, beginning with an initial assessment by the judges and followed by live online interviews in which shortlisted nominees presented their achievements and strategies directly to the judging panel.

These wins speak to what sets DIDWW apart: unlike providers who rent capacity from other operators, DIDWW directly holds the licenses and phone number blocks behind its services, in compliance with local regulators, keeping every call within its own network. That direct ownership is what makes it possible to keep going where other providers stop – into hard-to-reach, high-growth markets across Europe and beyond. With licensed local numbers in 30 countries, direct numbering resources in 19, and local partnerships bringing total coverage to over 90 countries, DIDWW gives mid-market and enterprise organizations a stable, compliant local presence wherever they need to do business.

“Being named Best Europe Provider and Best Voice Provider in the same year means a great deal to us,” said Karolis Jurys, CEO of DIDWW. “It's recognition of the team that shows up for our customers every day, and of the trust our customers and partners place in us to keep their voice services running, wherever in the world they're doing business. That trust is what motivates us to explore new markets and take on new challenges, so we can keep turning complex telecom problems into solutions that just work.”

SIP trunking delivers phone calls over the internet, replacing physical phone lines with a flexible, scalable connection that lowers telecom costs. It works by connecting a business phone system to a SIP trunking provider, which routes calls to the wider phone network without requiring new hardware. Key benefits include usage-based pricing, easy scalability, simplified expansion into new markets with local numbers, consolidated infrastructure, and compatibility with existing communication platforms. When choosing a provider, businesses should evaluate coverage, call quality, compliance, integration, and support.

If your business still runs phone calls over traditional phone lines, you're paying more than you need to, and you're limited in ways you might not even realize. Businesses commonly report saving 25% to 65% on monthly telecommunication expenses when switching from traditional phone lines to SIP trunking.

SIP trunking is the technology that lets you make and receive calls over the internet instead - and for most growing businesses, it's the difference between a phone system that scales with you and one that holds you back.

Here's what it is, how it works, and what to look for if you're evaluating it.

What is SIP trunking?

SIP trunking is a method of delivering business phone calls over an internet connection using the Session Initiation Protocol (SIP), it replaces physical phone lines with a virtual connection that carries voice calls over your internet connection.

Instead of paying for a fixed number of copper lines running into your office, you get a flexible pool of calling capacity that you can scale up or down as your business needs change.

Think of it like the difference between owning a fleet of company cars and using a car-sharing service. With traditional phone lines, you own (and pay for) a fixed number of connections whether you're using them or not.

How SIP trunking works

SIP - the technical standard used to set up, manage, and end a voice call over the internet. A "trunk" is simply the connection carrying multiple calls at once, the same term used for traditional phone lines.

In practice:

1. Your business phone system (cloud PBX, unified communications platform, etc.) connects to a SIP trunking provider instead of a physical phone line.
2. Calls travel as data over your internet connection rather than through dedicated copper wiring.
3. The provider connects those calls to the wider phone network, so you can call - and be called by - any phone number, anywhere.

No new hardware runs through your walls. No engineer needs to install physical lines. The setup lives in software and configuration, which is a large part of why it's faster and cheaper to change than a traditional setup.

Why businesses are switching to SIP trunking

• Lower costs: Traditional phone lines charge you for capacity you may not use, especially outside business hours or during slow periods. SIP trunking is typically priced around actual usage, so you're not paying to keep idle lines connected.
• Room to scale up or down without a truck roll: Adding capacity for a busy season, a new hire, or a new office location is a configuration change, not a hardware install. The same goes for scaling down - you're not locked into infrastructure sized for your busiest month.
• Easier expansion into new markets: If you want a local phone number in another city or country so customers there can reach you at local rates, that's something SIP trunking makes straightforward - no need to lease physical infrastructure in that location.
• One connection, less to manage: Consolidating your voice traffic onto your existing internet connection means fewer separate vendors, fewer physical lines, and typically simpler IT overhead.
• Works with the tools you already use: SIP trunking is built to connect to modern cloud PBX and unified communications platforms like 3CX, Yeastar, Microsoft Teams, etc. - so it fits into infrastructure you're likely already running rather than requiring you to rip anything out.

What to check before you choose a provider

Not all SIP trunking providers are the same, and the differences matter once you're relying on it for business calls. Some things worth asking about:

• Coverage: Where does the provider actually offer phone numbers and connectivity? If you operate internationally or plan to, check that coverage matches your footprint. It’s also worth looking at the provider’s licenses, whether they have their own number ranges, and whether it can offer connectivity in harder-to-reach or less commonly covered locations.
• Call quality and reliability: Ask about uptime commitments and how the provider handles call quality, since voice traffic is more sensitive to network issues than most other data.
• Compliance: Depending on where you operate, there may be local regulatory requirements around phone numbers that vary by country. It’s worth confirming these requirements upfront, rather than discovering them after signing up.
• Integration: Confirm the SIP trunk service works seamlessly with the PBX or communications platform you already use, or plan to use.
• Support: Voice is often mission-critical, so it is essential that a provider offers 24/7 support. Check that some form of support is available around the clock - it’s especially critical when issues arise outside standard business hours.

Why over 7000 businesses choose DIDWW

DIDWW is licensed voice infrastructure - not a reseller renting someone else's network, but the operator directly holding the licenses and number blocks that keep businesses connected in 90+ countries. That's the difference between connectivity that's dependable and connectivity that just claims to be.

INVADE shows what that looks like in practice. Its predictive dialing platform powers market researchers in 50+ countries, scaling from small teams to operations running more than 1,000 interviewers - and at that range, voice connectivity can't be a weak link. It has to hold up whether you're placing ten calls a day or ten thousand.

That's what DIDWW's SIP trunks deliver: connectivity that scales with INVADE rather than around it, backed by a network DIDWW owns end to end - so call quality and uptime don't depend on someone else's infrastructure decisions.

"DIDWW has helped to facilitate our migration from on-premise to the INVADE 'Dialler as a Service' model by making it simple and cost effective for us to manage all of our client's SIP requirements in-house." - shared Mark Baker, the CEO of INVADE.

Running on DIDWW's own global network, INVADE gets virtually unlimited call capacity, flexible trunk configurations, and premium audio quality as standard - so wherever their research takes them, the connection behind it just works.

Lower costs. Simpler infrastructure. Reliable communications that scale across markets.

That’s the advantages of SIP trunking - and what DIDWW enables businesses like INVADE to achieve on a global scale.

Conclusion

SIP trunking turns business phone calls into something flexible, scalable, and easier to manage than traditional lines - and the benefits go well beyond just cost.

With SIP trunking, businesses gain the ability to scale capacity up or down instantly, without waiting on hardware installs or truck rolls. Expanding into new markets becomes simpler too - local numbers can be added wherever your customers are, without leasing physical infrastructure in each location. Because voice traffic runs over your existing internet connection, there's less to manage overall: fewer vendors, fewer physical lines, and a communications setup that fits cleanly into the cloud PBX or unified communications platform you're already using.

The result is a phone system built for how modern businesses actually operate - global by default, responsive to demand, and free from the rigid constraints of copper lines.

If your current setup is costing more than it should, buckling under growth, or holding back your expansion into new markets, SIP trunking is must-switch.

DIDWW provides one SIP trunking solution - inbound and outbound, built to keep call quality steady and downtime out of the picture. DIDWW offers premium voice routes through carrier-grade infrastructure with 99.998% uptime, plus local coverage in 55+ countries. SIP trunks can be configured to match how your business actually operates - with no vendor lock-in and native integrations with platforms like ElevenLabs, Retell AI, Vapi, Microsoft Teams, and Genesys.

Most of the tools are writes, not reads: this isn't just an agent that checks status, it's one that gets things done. Same authorization rules as the self-service user panel apply throughout.

Agents can:

• Phone numbers - Search coverage, review pricing, purchase and manage DID numbers.
• Inbound routing - Create and manage SIP, PSTN, and phone.systems™ trunks, configure failover and load balancing.
• Messaging - Manage SMS trunks, groups, routing, and DID assignments.
• Capacity - Review, purchase, and assign voice channels.
• Billing and payments - Review balances, invoices, orders, payments, refunds, and saved payment methods.
• Exports - Prepare and download supported call-record, SMS-log, DID-number, order, and payment exports.
• Compliance and verification - Manage identities, addresses, documents, and verifications.
• Emergency calling - Review requirements, create supported services, and submit or resubmit emergency verifications.
• Users and invitations - Review account users and manage supported user invitations.

How access works: The connection uses OAuth authorization - your agent acts as the DIDWW user who approved it, with the same roles and permissions that apply in the User Panel. No password or API key is entered in the MCP client. Protected actions - purchases, terminations, significant changes - use a two-step confirmation so you review before anything is applied.

Compatible MCP clients include Claude, ChatGPT and Perplexity. Other remote MCP clients may also connect.

This is early-stage technology, and adoption will be gradual. We invite technical teams to try it out and share feedback.

Dublin, Ireland - September 9, 2026 – DIDWW, a licensed voice and messaging infrastructure provider operating in 90+ countries, has expanded its Application-to-Person (A2P) SMS service to Croatia, Romania, Belgium, and Norway, bringing its A2P SMS coverage to 53 countries. The expansion further extends DIDWW’s messaging infrastructure across Europe, giving businesses access to A2P SMS capabilities in four additional destinations.

Croatia, Romania, Belgium, and Norway mean businesses can send authentication codes, reminders, and customer notifications in four more markets – through the same API, the same panel, and the same delivery reporting they already use. It's DIDWW's own licensed infrastructure behind every message, not a reseller relationship, which is what keeps deliverability and Sender ID options consistent as coverage grows.

Reaching customers matters as much as how the message is presented to them. DIDWW's A2P SMS supports alphanumeric, long-code, and carrier Sender IDs, giving companies options suited to different markets and messaging needs. Campaigns stay just as easy to manage – the same delivery reporting and campaign tools apply whether messages go out through the DIDWW SMS API or the self-serve User Panel.

"Businesses don't build their customer base one country at a time anymore. They expect their messaging to keep up with wherever their customers are," said Tadas Urbietis, Carrier Relations Manager at DIDWW. "Adding Croatia, Romania, Belgium, and Norway means our customers can grow into these markets without adding a new vendor or a new process. That's the kind of expansion we want to keep making."

AI agents are intelligent, autonomous applications that can understand requests, process information, make decisions, and take action without constant human oversight. They enable organizations to provide 24/7 support, automate repetitive work, reduce operational costs, increase productivity and accuracy, improve decision-making, and strengthen compliance. From conversational and voice agents to workflow automation and fully autonomous systems, AI agents are transforming customer service, IT, sales, marketing, retail, healthcare, financial services, and countless other industries.

Customers don't want to wait. They want an answer at 2 a.m., a resolution on the first try, and service that still feels personal - at scale. Most teams can't hire fast enough to close that gap.

That's the problem AI agents solve. They deliver instant, consistent service without adding headcount, freeing your team to focus on the work that actually needs a human touch - which is the real reason adoption is moving so fast: 85% of enterprises already use AI agents in their business operations.

What are AI agents?

An AI agent is software that uses AI to complete one specific job on its own - answering support tickets, booking rooms, scheduling meetings.

Think of it as a digital employee with one specific job. It works within clear boundaries and does that job well. It can make decisions related to its role, but unlike a person, it isn't switching between lots of different tasks or juggling multiple responsibilities at once.

AI agents vs. agentic AI

“AI agent” and “agentic AI” sound interchangeable. They're not.

An AI agent follows instructions to complete a task. Agentic AI figures out the goal itself and adjusts its plan along the way.

Why AI agents matter

It comes down to one thing: AI agents help you deliver what customers actually want - fast answers, consistent quality, lower costs - without growing headcount at the same pace.

•     24/7 availability: Round-the-clock support and monitoring, so the business stays responsive in every time zone.

•     Lower operating costs: Automates repetitive work - data entry, scheduling, basic ticket handling - so you scale without scaling headcount.

•     Greater team productivity: Takes routine work off employees' plates, freeing them for strategy, innovation, and the relationships that need a human touch.

•     Data-driven decisions: Analyzes large volumes of data in real time to spot trends, predict demand, and surface insights that speed up decision-making.

•     Higher accuracy and compliance: Cuts human error and checks its own output against internal policies and business rules, keeping quality and compliance consistent.

How AI agents work

Every AI agent, whatever the type, runs the same basic loop: take in a request, gather what it needs, decide what to do, then act.

1.   Receive a request: the user hands over a task.

2.   Process the information: the agent reads the request and pulls in relevant data.

3.   Perform the task: it takes the action - answering a question, generating a report, updating a system.

4.   Deliver the result: the output goes back to the user.

Example: a customer service AI agent gets a question, searches the knowledge base, drafts an answer, and sends it back - all in seconds.

AI agent types

Not every job needs the same kind of judgment. Here's how the main types line up.

Conversational and voice agents

These agents talk to people naturally, by text or by voice.

•     Voice AI agents: Voice AI agents hold natural phone conversations using speech recognition, language understanding, and realistic voice generation. They answer calls, manage support lines, qualify leads, and keep the conversation going even in noisy environments. Examples: ElevenLabs, Vapi, Retell AI, Synthflow AI.

•     Conversational AI (chatbots): Chatbots answer questions, schedule appointments, and troubleshoot issues over text, instantly and around the clock. Examples: Zendesk AI, Microsoft Copilot Studio, Intercom Fin.

Workflow and automation agents

These agents connect your systems and complete tasks automatically once certain conditions are met.

•     Process-driven agents: Handle repetitive, rule-based work - updating CRM records, organizing spreadsheets, sending follow-up emails - with little human involvement. Examples: Zapier AI, Make, UiPath, Microsoft Power Automate.

•     Workflow agents: Go a step further, weighing a situation and deciding what happens next - reviewing content against brand guidelines before it publishes, or routing a request to the right team based on context. Examples: Salesforce Agentforce, CrewAI, ServiceNow AI Agents.

Agentic and autonomous agents

The most capable of the three. Instead of just responding, they plan, reason through complex problems, use outside tools, and work toward bigger goals with minimal oversight.

•     AI assistants: Built into your daily tools - Google Workspace, Odoo - to draft documents, summarize meetings, manage email, and handle tasks you authorize. Examples: Microsoft 365 Copilot, Google Gemini, Claude AI, ChatGPT.

•     Coding assistants: Review code, suggest improvements, generate new features, run tests, and help find and fix bugs. Examples: GitHub Copilot, Cursor, Codex, Windsurf.

•     Research agents: Work through large volumes of documents, databases, and online sources to gather information, summarize findings, spot trends, or flag issues like broken links and outdated content. Examples: Perplexity Enterprise, NotebookLM, Glean, Elicit, Harvey (for legal research).

Conclusion

AI agents aren't a future consideration - they're already reshaping how businesses handle customer interactions and daily operations. The real question isn't whether to adopt them, but which type fits the job in front of you.

For voice AI agents, even the smartest model in the world still needs a voice infrastructure that works. DIDWW provides that connection - phone numbers in over 90 countries, premium voice routing, business messaging solutions, and seamless compatibility with ElevenLabs, Retell AI, Vapi, and any BYOC-compatible platform.

VoIP fraud is an increasing risk for businesses, with attacks such as toll fraud, caller ID spoofing, PBX hacking, and call interception exploiting weak security and configuration gaps. Strong authentication, timely updates, secure configurations, network monitoring, employee training, and encryption are essential to preventing unauthorized access and protecting communications.

Companies around the world have already fallen victim to VoIP-related fraud. A single incident can cost an enterprise anywhere from $3,000 to $50,000 - or even more.

VoIP fraud is the unauthorized use of Voice over Internet Protocol systems to place calls, steal data, or execute scams, typically without the victim’s awareness.

Cyber attackers are not only interested in large organizations or direct financial theft. They actively exploit unsecured VoIP systems, using them to carry out scams, make fraudulent calls, or run large-scale attack campaigns. In some cases, attackers don’t even need to generate direct billing costs - your system alone can become a tool in someone else’s fraud operation.

The real question is: is your infrastructure ready to defend against this kind of misuse?

In this article, we take an in-depth look at different types of VoIP scams and how they work, along with essential steps you can take to secure your systems and protect your business from these evolving threats.

Types of VoIP scams

As businesses increasingly adopt VoIP technology, cybercriminals have developed various methods to exploit organizations that do not properly secure their phone systems. Some of the most common types of VoIP scams include:

Toll fraud

Toll fraud is one of the most financially damaging forms of VoIP abuse. It occurs when attackers gain unauthorized access to a company’s VoIP environment - such as a PBX system, SIP trunk, or voicemail platform - and use it to place outbound calls to premium-rate or international numbers under their control. The organization whose system has been compromised is then billed for these calls, often discovering the fraud only after receiving unexpectedly high telecom charges.

How does toll fraud work? Attackers typically begin by scanning internet-facing VoIP systems for exposed SIP services or poorly secured administrative interfaces. Weak passwords, default credentials, and unpatched software are common entry points. Once access is obtained, automated scripts can generate thousands of simultaneous calls, often during nights, weekends, or holidays when monitoring is limited. These calls are placed to premium rate numbers - that charge callers at a higher rate.

The impact of toll fraud can be severe, with organizations facing losses ranging from hundreds to hundreds of thousands of euros or dollars in a matter of hours. A small business in Perth fell victim to this type of fraud after attackers compromised its phone system and placed more than 11,000 unauthorized international calls over a 46-hour period - charges exceeding $120,000.

Caller ID spoofing

Caller ID spoofing is a technique in which attackers deliberately falsify the caller identification information displayed on a recipient’s phone. VoIP systems make caller ID manipulation relatively easy because call signaling protocols, such as SIP, can allow caller identity information to be modified unless additional validation mechanisms are in place.

How does caller ID spoofing work? Scammers begin by impersonating a legitimate phone number, such as one belonging to a bank, government agency, customer service center, or internal corporate extension. Before placing a call, the attacker modifies the caller ID information through a compromised PBX system or insecure SIP trunk to display a trusted number.

This significantly increases the likelihood that the recipient will answer the call and trust the caller's instructions.

Caller ID spoofing is commonly used in vishing (voice phishing) campaigns, technical support scams, debt collection fraud, and business email compromise scenarios that involve voice communication. Reports indicate that, so far in 2026, 70% of organizations have experienced at least one vishing attack.

Spoofed calls may also be used to bypass basic trust mechanisms within organizations. For example, employees may comply with requests if the incoming call appears to originate from senior management or internal IT departments.

PBX system hacking

PBX (Private Branch Exchange) system hacking involves unauthorized access to an organization’s telephone exchange system, particularly IP-based PBX platforms. Modern IP-PBX systems manage internal and external voice communications, voicemail, conferencing, and routing services, making them high-value targets for attackers.

Attackers often target exposed web administration panels, SIP services, remote management interfaces, or voicemail systems protected by weak credentials. Automated scanning tools can identify vulnerable PBX systems connected to the internet, after which attackers attempt brute-force logins, exploit software vulnerabilities, or abuse misconfigured services.

How does PBX system hacking work? Once inside the PBX environment, attackers may create new user accounts, modify call routing rules, enable unauthorized forwarding, record conversations, or use the system for toll fraud. In some cases, attackers maintain persistent access, allowing long-term surveillance or repeated financial abuse.

Because PBX systems often integrate with corporate networks, a compromised PBX may also serve as an entry point for broader network attacks.

One of the largest telecommunications fraud operations on record was the Noor Aziz/Qasmani Global Scheme. In this case, foreign hackers targeted U.S. corporate PBX systems, reprogramming unused phone extensions to enable over $50 million in fraudulent calls. The proceeds were laundered through about 650 bank accounts in ten countries before coordinated international arrests were made.

Eavesdropping and call interception

Eavesdropping is the unauthorized interception of voice communications. In VoIP systems, voice is transmitted as digital packets over IP networks, so if traffic is not properly secured, attackers may capture and reconstruct conversations.

Common methods include packet sniffing on unsecured networks, compromised routers, open Wi-Fi, or malicious access points. More advanced attacks use man-in-the-middle (MITM) techniques, where attackers position themselves between two parties to intercept calls in real time.

How does eavesdropping and call interception work? A VoIP conversation is split into many small packets. Attackers can capture these packets, identify those belonging to a call, reorder them using sequence data, and reconstruct the audio. If SIP credentials are compromised, attackers can perform registration hijacking. They may register their device instead of the legitimate user, redirecting incoming calls to themselves. This allows them to answer, forward, record, or impersonate the user without detection.

This type of attack allows a fraudster not only to intercept communications, but also to actively participate in them without the legitimate user’s knowledge.

A notable example occurred between mid-2024 and early 2025, when major U.S. telecommunications providers - including AT&T, Verizon, Lumen Technologies, and T-Mobile - were targeted by a state-linked threat group known as Salt Typhoon.

The campaign affected sensitive communications across both government and private-sector organizations and is widely regarded as one of the most significant telecommunications breaches in U.S. history.

Essential security practices

To reduce the risk of VoIP fraud and cyberattacks, businesses should prioritize essential security measures.

Strong authentication and access control

Yes, ‘Name123’ is an easy-to-remember password, but it is also very easy for someone else to figure out. Instead, use strong, unique passwords for all VoIP accounts, voicemail systems, and administrative interfaces, and enable multi-factor authentication where possible. Default credentials should always be changed, and remote access should be limited to trusted networks or VPN connections.

Regular updates and secure configurations

Keep VoIP software, firmware, and PBX systems regularly updated to patch known vulnerabilities. Unnecessary services, open ports, and exposed management interfaces should be disabled to reduce the attack surface.

Network monitoring and call restrictions

Monitor call activity in real time and configure alerts for unusual behavior, such as high call volumes, after-hours activity, or unexpected international calls. Restrict access to premium-rate and international dialing unless it is required for business operations, and implement CAPS (Call Attempts Per Second) restrictions and spending limits to control call charges, prevent unauthorized usage, and reduce the risk of toll fraud.

Encryption and network protection

Transport Layer Security (TLS) protects SIP signaling by encrypting call setup and control messages, while Secure Real-time Transport Protocol (SRTP) encrypts the audio stream itself. When properly implemented, these technologies prevent attackers from easily decoding intercepted packets, even if network traffic is captured. Securing wireless networks and separating VoIP devices from the main corporate network can further reduce the risk of interception.

Employee awareness and verification

Train employees to recognize social engineering attempts such as vishing and caller ID spoofing, and to avoid trusting caller identity alone. Sensitive requests, especially involving payments, credentials, or confidential information, should always be verified through an independent communication channel.

Continuous auditing and incident detection

Regularly review system logs, access records, and configuration settings to identify suspicious activity early. Continuous monitoring and routine security audits help detect unauthorized access before it results in financial loss or operational disruption.

Conclusion

Cybercriminals' tactics continue to evolve, and organizations must keep pace by continuously strengthening their systems through regular updates, advanced threat detection, employee training, and strong data protection.

Cybersecurity should be viewed not only as an IT responsibility but as a core part of business strategy and risk management. Companies that prioritize it are better positioned to protect sensitive data, maintain customer trust, and minimize the financial and reputational impact of cyber incidents.
