Reduce your call center costs implementing SIP trunking to your dialing systems! Once you start turning over to the VoIP culture, you will realize how many goodies are waiting to be part of your call center. This article is to discuss about SIP and SIP Trunk.

What does SIP trunk stand for?

Well let’s talk about SIP first. SIP stands for Session Initiation Protocol, which works along with other protocols’ elements as the ‘HTTP’ and ‘SMTP’ protocol. Created in 1996 by Henning Schulzrinne and Mark Handley, SIP is born to focus in call setup and signaling. It does need proxy servers to perform the dialing, ringing, busy tones or in call ringing operations, as well as the call agents. It comes to control multimedia communication sessions relying on IP networks to facilitate that communication.

So this SIP gateway, may have several trunks (let’s think of trunks as channels or ports) that at the same time are connected to different carriers, which will be chosen to route the call to by the SIP proxy server. SIP trunking comes to adopt VoIP for the call’s connection while PSTN gateways are still functioning on the other end of the call, using IP-PBX; on both, inbound and outbound calls. SIP can be tested for very short time in order to implement its working with the PBX or dialer already installed in your VoIP call center.

Internet Telephony Service Providers ITSPs offer SIP trunking as a part of their call center solutions, along with their VoIP telephony systems.
Other SIP applications include conference calls, video conference calls, multicast, media streams, instant messages, faxes and various forms of online data transfer.
