Unified Communication and telephone services are delivered through SIP trunking using an IP network as a substitute for the normal telephone system. Using SIP trunking a VoIP user is able to make calls to any phone which belongs to a PTSN network without the need for telephone lines. Connections are established using a suitable hosted PBX solution.
There are three elements required for a SIP trunk to function properly. The first is the SIP provider who supplies the service, the second is a phone system with SIP enabled capabilities and thirdly a border element. This border element enables the connection between the enterprise network and the PTSN or an IP network.
The elements are often managed by the SIP trunking provider and they can be either a switch or firewall. Using these three basic components, a business is able to significantly improve its reach in terms of communications. If an IP-PBX has already been installed this will facilitate the process even more.
