SIP Trunking: A Cost-effective Telephony Alternative for Businesses


By Mini Swamy SIP Trunking Report Contributor



As VoIP technologies gain momentum in an ever evolving communication landscape, carriers and ISPs are offering business customers lower cost alternatives to traditional PSTN interconnects. Telx Telecom, Miami's popular service provider, is in the race and is now providing companies with SIP trunking alternatives to enhance phone system operations.


So let's see what SIP trunking is all about and why Telx Telecom is keen on offering this alternative to enterprises.

SIP (Session Initiated Protocol) is the industry protocol that is used when interactive user sessions are initiated over a data connection, and a trunk is medium that carries the signals. SIP Trunking uses VoIP to connect private branch exchanges (PBX) to the Internet. As the Internet takes the place of the telephone lines, enterprises can communicate with subscribers throughout the world.

So, for SIP trunking to happen, there must be a PBX in the enterprise that connects end users and an Internet telephony service provider (ITSP) that allows them to connect to the Internet. The Internet replaces the common telephone trunk, allowing companies to communicate with users.

Telx Telecom, which has always tried to simplify telecommunications for organizations and give them more benefits, is advocating SIP trunking as an alternative that will realize immediate and substantial cost saving, especially for long distance services. Another significant advantage is that data, voice, video can all be made to converge onto a single line. This is not only less expensive but also more reliable.

As SIP trunks allow users to directly connect to the ITSP, the gateway that exists between traditional PSTN interconnects and the ITSP can be dispensed with. In fact, if the ITSP offer a hosted PBX, then enterprises don't even require a PBX. This way the complexity is removed, no upkeep is required and organizations save substantially.

With SIP Trunking, subscribers can make and receive local and long distance calls, make emergency calls, access directory assistance and even e-mail and text.

If customers can invest a little, Telx Telecom believes that they can gain a lot by opting for SIP trunking.
