The phrase “SIP Trunking” or “SIP Trunks”, is becoming increasingly common in the business world, particularly in the telecommunications industry. SIP trunking, or Session Initiation Protocol trunking, is one way of connecting your company’s phone system to the Public Switched Telephone Network (PSTN), that is, the conventional message switched telephone network.
Before calling your local SIP trunking provider, though, first things first, what exactly it SIP.
What is SIP?
In the telecom industry, more businesses are using SIP for making phone calls on the Internet. It is the technology used for establishing a voice communication session on a data network. A SIP “session” may be anything from a regular VoIP phone call, or a phone call using the Internet, to a multi-party business conference call.
SIP helps simplify business communication, simultaneously connecting a wide range of communication devices, and employing a number of different applications to create a larger communication framework.
What Is SIP Trunking?
A SIP Trunk, meanwhile, provides the same service you get from traditional analog phone lines. The difference is that instead of using a physical wire, a SIP trunk is a ‘virtual’ phone line. Your London office, for example, can get this service through a reliable SIP trunk provider in the United Kingdom. They will use your data circuit, be it a T1 connection, DSL, or cable modem and use it to connect your phone system back to their network.
Why Switch to SIP?
A SIP Trunk is often considerably more affordable than traditional phone services, as VoIP communications tend to cost less. Moreover, SIP trunking eliminates the need for physical lines and constant maintenance. Depending on the type and number of calls your company makes, SIP Trunking can save you up to half or more on your monthly phone bills.
SIP trunking opens a new scope of establishing other types of real-time communications beyond your local area network. It also can be more reliable than traditional PSTN, since there are a number of failsafe solutions. Unlike traditional telephone services, there’s no need for bundles of physical wires with an SIP trunk, which allows businesses to replace traditional fixed PSTN lines with PSTN connectivity via a SIP Trunking service.
In today’s business world, efficiency is becoming more and more crucial. When it comes to your company’s telecommunications needs, anything that boosts performance and improves reliability, without costing you too much (such as SIP trunks) should definitely be something worth considering.
