SIP trunking is growing steadily in popularity as the preferred way of deploying VoIP. The other way to arrange a VoIP telephone system is to have a hosted IP PBX, which means you don’t have to worry about obtaining the hardware or setting up the SIP trunking yourself as the VoIP system will be pre-configured for you.

This allows more flexibility in the selection of the IP-PBX hardware and software required, providing a more tailored solution for each business. SIP trunks are deployed to connect the PBX with the telephone network, thus replacing the need for legacy phone lines or Primary Rate Interface. SIP trunking is a system that delivers telephone services and communication requirements to businesses who have SIP-enabled PBX and unified communication resources. SIP is also capable of generating Call Detail Records (CDR) for invoicing purposes. SIP acts as the signalling protocol within a VoIP telephone system and can manage all of the call requirements such as establishing the request, controlling the call, and ending the call. SIP can hook up new sessions to already occurring sessions like in the instance of a multicast conference and can be used for instant messaging, media distribution, and other applications. SIP is an application layer protocol which is put to work to set up, change, and terminate multimedia sessions just like VoIP telephone calls. VoIP technology is used with applications like Skype or Google Talk, with any IP-enabled PBX hardware or through a hosted VoIP telephone service.
