SIP stands for Session Initiation Protocal and a SIP Trunk is a network interface device that recognizes SIP signals, processing them to other SIP devices. SIP is important for V1 VoIP resellers to be informed about because they can save your customers up to 70% over traditional phone lines. SIP Trunks need to be explained as the way of the future.
SIP is the signal used instead of a phone line to establish a connection such as a telephone call, IM-Instant Message, conference call or other type of communications on an IP-Internet Protocol network. SIP operates like a “communications browser” protocol such as HTTP-Hypertext Transfer Protocol. It is the communications equivalent to such internet protocols such as HTTP and SMTP-Simple Mail Transfer Protocol (SMTP).
Calls placed over the Internet are placed via a media gateway on the service provider’s network. SIP Trunking will work with old key systems or new IP PBXs, offering advanced VoIP features. Unlike PRI lines which contain 23 channels, SIP Trunking can be purchased in increments as low as one concurrent call, so businesses buy only what they need as they need it.
In an IP and traditional telephony network, for a voice call to take place, it is expected that the two telephones go through two different phases known as call setup and call processing. The call setup – the first phase – happens when the two telephones want to talk to each other. This phase takes charge of exchanging all the information needed to get these two phones through and can start the call. In call setup phase, SIP has gradually replaced the well-known H323 is widely used. When the call has been setup, the call processing phase will begin to transfer voice data back and forth between the two phones.
