Session Initiation Protocol (SIP) is a standard signaling protocol used for the real-time delivery of voice, messaging, video, and other communications applications between two or more endpoints on IP networks. SIP trunking is a contemporary and increasingly common method for originating, maintaining, modifying, and terminating call sessions over the Internet.

Offering a number of great benefits, SIP trunking solutions can help reduce telephony costs, streamline all means of communications, and at the same time, allow for more flexibility and faster scaling. Let’s take a closer look at the real advantages of SIP trunking:

Cost-effective calling using SIP trunks

One of the main and well-known advantages of SIP trunking is its cost-effectiveness. The savings achieved are attributed to the elimination of capital costs for physical telephone lines, technology consolidation, and lower call rates. When using SIP trunking, long-distance and international calling is cheaper and is equivalent to the cost of local calls if used with a true local telephony provider.

Global scalability with SIP trunking

The SIP trunking mechanism is extremely flexible and very easy to scale up or down. This solution eliminates the need to invest in costly infrastructure and makes it easy to deploy voice services and scale communication systems on-demand. Furthermore, unlike traditional telephony providers, SIP trunking allows for an unlimited number of channels per trunk that can be added and activated in a matter of hours.

Elimination of location-based restrictions

Another benefit of SIP trunking is that it removes telecom-related, location-based restrictions and grants its users the ability to acquire any number, regardless of geography. Following all regulatory requirements, a SIP trunk provider may interconnect with national networks in each and every country to deliver fully compliant and streamlined services all around the world.

High-quality calls and system reliability

SIP technology empowers an extremely reliable phone system, providing high-quality voice services and ensuring redundancy in the event of power outages or system failures. However, the smooth functioning of SIP trunking, the call quality and service reliability are very much dependent on the choice of a trusted and compliant telecom operator.
