Throughout the rollout, DIDWW's responsive support team provided consistent guidance, helping Markit optimize the platform to meet the full demands of its global operations.

Managing calls and customer support across dozens of markets was becoming a real operational challenge. With phone.systems™, we finally have one system that works everywhere we do – and DIDWW's team made the whole process straightforward from day one.”

Vladas Juozapavicius, phone.systems™ Product Manager at DIDWW, commented: “Markit represents the type of globally distributed organization that needs truly scalable and flexible communication infrastructure.

Choosing a Cloud PBX provider starts with defining your business communication requirements and objectives. Key evaluation factors include essential features, CRM and software integrations, transparent pricing, reliable 24/7 support, and a platform that is regularly maintained and updated. Clear requirements make it easier to compare providers, avoid unnecessary complexity, and select a solution that best supports long-term business operations.

Most businesses report successful Cloud PBX migration. However, the minority still remains dissatisfied, often mentioning unmet expectations and a lack of preparedness for the transition.

This is often caused by insufficient research, unclear business goals, or overlooking essential features and integrations. In fact, more than 50% of CIO's research respondents identified a lack of clearly defined business objectives as a major challenge in cloud migration.

Thorough research and careful planning are essential to choosing the right provider and avoiding disappointment. In this article, we will cover the key factors to consider when selecting a PBX provider.

What is a Cloud PBX system?

A Cloud PBX (Private Branch Exchange) is a business phone system that runs over the internet protocol instead of using traditional office phones and on-site equipment. It allows companies to make and receive calls, set up voicemail, and use other communication features entirely online.

PBX systems have been around for over a century. They started as manual switchboards, where operators connected calls by hand. Before automated systems, these switchboards acted as the central hub for all telecommunications. Later, they became automated, greatly improving efficiency and scalability.

Today, PBX systems operate in the cloud, making them more flexible, scalable, and cost-effective. Compared to traditional systems, Cloud PBX solutions offer greater flexibility and advanced features, but choosing the right solution still requires careful consideration.

Key Cloud PBX features

The features offered by a PBX provider can vary widely, the right solution should align with your organizations communication goals, operational workflows, and future growth plans. Some of the most important PBX features to evaluate include:

• Call routing and call forwarding: Ensure your business phone system is able to route incoming calls to the right departments, teams, or remote employees based on business hours, caller preferences, IVR (Interactive Voice Response) menus, or custom routing rules.
• Voicemail and voicemail-to-email: Modern PBX phone systems should offer professional voicemail functionality, including voicemail transcription and voicemail-to-email delivery.
• Conference calling: A reliable business communication system should support audio conferencing to keep internal teams and external clients connected.
• Call analytics and reporting: Detailed call reporting, call analytics, and real-time dashboards provide valuable insights into call volumes, agent performance, customer wait times, and overall communication efficiency, helping businesses optimize their phone operations.
• Mobile app and remote connectivity: With hybrid and remote work becoming standard, a mobile app allows employees to make and receive business calls, access voicemail, transfer calls, and manage communications from smartphones, tablets, or laptops.

Prioritize features based on your business size, industry, and communication needs, while choosing a provider that actively invests in product development. Regular feature updates and system improvements help ensure your Cloud PBX remains modern, secure, reliable, and capable of supporting your business as it grows.

Cloud PBX integrations

When choosing a Cloud PBX provider, it’s important to consider how well the system integrates with your current business tools - and any platforms you may need to adopt in the future.

One of the most valuable integrations is with a CRM (Customer Relationship Management) platform. The most widely used CRM platforms are Salesforce, HubSpot, Pipedrive, and Zoho CRM, so there’s a good chance your business already uses one of them. Make sure the PBX provider offers an official integration with your CRM.

Why does this matter? Official integrations ensure seamless compatibility between systems, and easy setup. An unofficial integration can lead to potential errors, require significant manual work and troubleshooting, and may not sync reliably or effectively.

Ultimately, choosing a PBX that integrates well with the third-party platforms your business relies on is one of the most (if not the most) important factors to consider.

Cloud PBX pricing

Cloud PBX pricing varies by provider. Some providers charge per user, offering flexibility as teams grow, while others provide flat monthly or annual pricing for more predictable budgeting. It is important to check what’s included and watch for any potential hidden costs like setup fees, integrations, international calls, or advanced features.

Typical pricing includes:

• Small businesses: $20-$40 per user/month
• Larger teams: $10-$25 per user/month with volume discounts

Common plan tiers:

• Basic plans: Voicemail, auto-attendants, softphone app
• Pro plans: CRM integrations, call recording, AI transcription
• Enterprise plans: Advanced analytics, multi-site support, dedicated service

Additional costs may include hardware, number porting, and onboarding fees.

Support and onboarding

Reliable customer support is an important factor when choosing a Cloud PBX provider. Look for providers that offer 24/7 technical support, multiple contact channels, onboarding assistance, and comprehensive documentation.

Despite the rise of AI-powered support, research shows that 84.7% of participants prefer human interaction over communication with an AI agent. Providers that offer timely access to human specialists are often better equipped to handle urgent or complex issues.

Customer reviews, case studies, and testimonials can also provide useful insight into a provider’s responsiveness, problem-solving ability, and overall service quality.

The countdown has already begun - and for traditional landlines, there is no pause button.

The global telecommunications landscape is undergoing one of its most significant transformations in decades: the global Public Switched Telephone Network (PSTN) switch off, with approximately 2.4 million businesses in the UK alone, are estimated to be affected by this change - B4BC.

Businesses that rely on traditional landlines must now prepare for a full transition to internet-based communications, most commonly Voice over Internet Protocol (VoIP). Understanding what is changing, when it is happening, and how to respond is essential to maintaining business continuity. In this article, we take a closer look at what this transition means and how to navigate it effectively.

What is the PSTN switch off?

The Public Switched Telephone Network (PSTN) is the traditional copper-based infrastructure that has carried voice calls for over a century. This infrastructure is now being permanently phased out and replaced with digital networks.

There are several reasons as to why the switch off is happening, main ones include the price, technological shift, and improved efficiency.

Copper lines are too expensive to maintain, and the companies and institutions that maintain them are desperate to get rid of them. VoIP has been around for a long time now and has only gotten better. Modern communications rely on broadband and cloud-based services. VoIP and fibre networks offer greater scalability, flexibility, and feature-rich communication - modern businesses just have no reason to be tied to outdated systems that do not have advanced features like VoIP, cloud solutions do.

Key deadlines in different countries

While timelines vary by country, the global direction is consistent: PSTN networks are being retired in favour of digital alternatives.

Key timelines for PSTN switch off around the world:

United Kingdom

Openreach, the largest wholesale broadband and telephone network in the UK, originally announced the intention to retire the analogue network by December 2025, a date that was later delayed. Since September 2023, the company has no longer offered new traditional copper-based landlines or ISDN services.

Full PSTN switch-off in the UK is expected by 31 January 2027.

The European Union

Many European Union countries have already largely completed the transition away from PSTN networks. Estonia, Germany, the Netherlands, Sweden, and Norway have migrated most copper-based telephony to digital systems. Other countries are still phasing out PSTN services.

Disconnections in Belgium began in fiber-ready areas in 2022 and are still in progress. Denmark plans to fully retire traditional telephony by 2030. In France, Orange is managing the gradual switch-off, targeting completion by 2030.

United States

The US PSTN is being phased out, with major carriers like AT&T targeting 2027 to 2029 for final copper line retirement, transitioning to digital Fiber or VoIP services. The FCC has eased restrictions on carriers to accelerate the retirement of copper lines, encouraging migration to IP-based networks.

There is currently no fixed deadline for the U.S. PSTN switch-off. However, if you are a business operating in the U.S. with a U.S. carrier, your provider is required to notify you at least 180 days before your services are shut down - fcc.gov.

Australia and New Zealand

Many providers have already begun decommissioning copper-based telephone lines, replacing them with modern VoIP solutions as part of the wider transition to all-IP networks. This shift reflects a broader move away from legacy PSTN infrastructure toward more flexible, scalable, and cost-efficient digital communication systems.

Both countries are currently working toward completing their full PSTN switch-off by 2030.

Japan

Japan is in the final stages of its PSTN shutdown. NTT, a major telecommunications provider in Japan, began migrating services away from traditional PSTN infrastructure around 2010, gradually preparing for a nationwide shift toward digital communication systems.

The goal is to fully retire the legacy network for most customers by 2028.

Although deadlines differ - it may not seem that there is a hurry to switch right now. However, the global trend is clear: legacy telephony is being replaced everywhere, and businesses must act proactively rather than wait for enforced cut-off dates. Better to act sooner rather than later.

Preparing for the transition

This is the most critical part of the process. A successful migration to VoIP requires planning, auditing, and careful execution.

Understanding and auditing your existing communications setup involves identifying everything connected to your PSTN lines:

• Desk phones and PBX systems
• Fax machines
• Alarm systems and elevator emergency phones
• Payment terminals and card machines
• Broadband services running over copper lines

Many businesses are surprised by how many systems depend on PSTN, and the Open Access Government “iceberg” analogy clearly highlights the scale of the shutdowns' impact.

Defining your requirements is important before selecting a VoIP solution. Take the time to assess your organisation’s needs:

• Number of users and locations
• Call volume and peak usage times
• Integration with CRM or collaboration tools (e.g. Microsoft Teams)
• Any additional system integrations (such as billing, automation, or other business software)

This step ensures you choose a system that supports future growth, not just current needs.

Planning the migration carefully with a well-structured strategy helps minimise disruption:

• Move departments or sites gradually rather than all at once
• Keep PSTN and VoIP running simultaneously during transition
• Ensure you have enough time, and the right documents to port your existing numbers to your new provider.
• Test call quality, routing, and integrations before full cutover

Many providers recommend starting migration well before the official PSTN shutdown due to high demand closer to deadlines.

Supporting your team is crucial, as technology changes are only effective when employees are properly supported:

• Train employees on new calling systems and features
• Update call handling procedures and routing rules
• Inform customers if contact methods change
• Provide internal support during the transition period

This reduces downtime and ensures a smoother adoption process.

Ongoing optimisation after migration is essential, as continuous monitoring and improvement are key:

• Monitor call quality and latency
• Review system analytics and usage patterns
• Adjust call routing and auto-attendant settings
• Continuously optimise bandwidth and configuration

VoIP systems are flexible, and ongoing optimisation can significantly improve efficiency.

Conclusion

The PSTN switch off marks a crucial shift in how businesses communicate, moving from legacy infrastructure to more flexible, scalable, and future-ready digital solutions. While the transition may seem complex, it also presents a valuable opportunity to modernize communication systems, enhance reliability, and unlock new capabilities that traditional telephony simply cannot support.

Businesses that take a proactive approach - assessing their current dependencies, planning migrations carefully, and investing in the right VoIP or cloud-based solutions - will be best positioned to ensure seamless operations. Delaying action, on the other hand, risks disruption and potential loss of connectivity at critical moments.

Ultimately, this transformation is not just a technical upgrade, but a strategic evolution. By embracing the change now, businesses can future-proof their communications, improve efficiency, and stay competitive in an increasingly digital world.
