What is SIP Trunking?

A SIP (Session Initiation Protocol) Trunk supports multiple voice calls or voice channels, routed via an IP network like an MPLS Network or the Internet. An SIP trunk replaces fixed Public Switched Telephone Network (PSTN) lines with a flexible, feature-rich system with full PSTN connectivity.

If you already have an IP-PBX system, you can benefit from Convergia’s SIP Trunking service to save on all your local and long-distance calls. SIP Trunking supports the most popular IP PBXs, including: Avaya, Cisco, Mitel, Positron, Asterisk and more.

SIP Trunking – What Is It?

Session Initiation Protocol connects a variety of communications signals across the Internet, serving as a real time communication protocol for VoIP. Whether text, voice, video, or instant messaging, SIP works with PBX phone systems to combine voice trunking with high speed data access and ensure highly reliable performance and the best quality. SIP also works with analog telephones and other business telephone systems as well.

SIP Trunks recognize SIP signals and transmit these signals to other SIP machines. A Softswitch or SBC-Session Border Controller provides SIP Trunking and signal processing, protocol conversion, and many additional functions as well.

SIP Trunking Offers Flexibility

SIP Trunking is scalable, offering flexible bandwidth adjustment capability. This means you only use – and only pay for – as much or as little as needed. The IP media stream sent from your company remains as an IP media stream and goes anywhere within the company or to another company by IP, thus reducing the need for hardware media gateways while yielding considerable cost savings.

SIP Offers More Security and Savings

Save considerably with SIP, by eliminating the need for local PSTN gateways, expensive hardware, complicated network management tools and other extra costs. In addition, SIP significantly lowers security risks, via voice encryption.

Benefits of SIP Trunking

SIP trunks can offer significant cost-savings for small and medium sized businesses by eliminating the need for local PSTN gateways, PRIs (Primary Rate Interfaces) and expensive ISDN BRIs (Basic Rate Interfaces). Unlike the bundles of physical wires used in traditional telephony, a SIP trunk allows a business to replace these fixed PSTN lines with PSTN connectivity via a SIP trunking service provider on the Internet.

SIP trunks phone systems provide more flexibility and features

SIP trunks phone systems provide more flexibility and features than traditional business phone systems. Now, it is possible for a small business to have all the business telephone capabilities and features of a multi-national company at a very low cost.

There are so many other advantages of SIP trunks, like the ability to take your phone number with you around the world when you travel, local calling in cities that you don’t physically have an office in, integration between your phone system and customer management systems (CMS), advanced calling, voice mail options and much more.

The main advantage of SIP Trunks over PRIs is that SIP Trunks can be ordered in increments of 1, whereas PRIs have to be ordered in increments of 23 channels.
