What Is SIP Trunking?

Business Knowledge

Session Initiation Protocol (SIP) trunking is a type of service that is provided by a communications service provider. They use the method of voice-over IP (VoIP). In this, the connectivity between a phone system and the public switched telephone network. This type of connectivity is done at your premises.  SIP is used for making and managing calls. SIP trunking is a replacement of the digital Primary Rate Interfaces.  which is based on the time-division multiplexing.

SIP trunking is widely used and deployed by communications service providers. Many companies are replacing their TDM-based services. These service providers are giving SIP trunking on the existing Ethernet or on the Multiprotocol Label Switching (MPLS) network infrastructure. The providers also reduce the sip trunking cost and also remove some complexity that is associated with legacy digital platforms. They have a provision of adding some extra features to it.

Why we use SIP Trunking?

The main purpose to use the SIP trunking is to replace PRI technology, which is very old technology. PRI refers to a Primary Rate Interface. We are using this method for the last so many years to deliver lines of voice. With the help of copper lines, we are able to transfer the data. This method is very slow and it requires a lot to maintain the line because there are so many analog phone lines are connected, so it requires bundles of lines. So its hardware also becomes outdated.

SIP trunking is using VoIP technology. Which is refresh and faster also. In SIP trucking we can do instant messages and video conferencing also because sip supports all types of data transferring. SIP trunking is not so costly. This technology is the right option for those who want to start their communication business at less cost.
