Session Initiation Protocol (SIP) trunks are telephone line trunks delivered over IP using the SIP protocol. It is different from the traditional old phone lines to connect IP-PBX. SIP is the use of VoIP service to facilitate the connection of PBX or any SIP compatible devices over the internet. A SIP Trunk is a logical connection between an IP PBX and VoIP servers that allows voice over IP traffic to be exchanged between the two.
When a call is placed to an external number, PBX acts as an intermediary for the call and send the necessary information to the SIP Trunk provider who establishes the call to the dialed number. All signaling and voice traffic between the PBX and the provider is exchanged using SIP and RTP protocol packets over the IP network. By inserting the correct parameters into the IP-PBX (the model that supports SIP), you can use your IP-PBX to make outbound VoIP calls. A SIP Trunking service provider will provide a SIP username and SIP password and Registrar IP.
