SIP trunks are innovative means of implementing VoIP (Voice over Internet Protocol) that provides multipoint voice and unicast services over a standard IP network. A SIP trunking service assigns IP addresses to its subscribers. When a subscriber wants to make a call, he uses the address of the SIP trunk in order to connect to the system’s SIP server.

It is necessary to install software that helps a SIP server to process incoming calls and route them to appropriate destinations and to set up firewall software that helps block unwanted calls that may be made to another IP telephone or SIP server.
Finally, SIP servers often have a higher price compared to dedicated IP telephones because they need more space to store their configuration information. These servers can also be more difficult to manage. setup than dedicated IP telephones.
