Signalling

VoIP service needs to use a protocol to signal the calls. The signalling protocol used by IPBrick is SIP, but there are others such as H.323, MGCP, Jingle, IAX, H.248/MEGACO etc. SIP4.16 allows calls and conferences through IP, and those calls may include audio, video and images etc. This way, the SIP protocol is responsible for all the process of calls between the users independently from the type of contents of the call itself. The IPBrick.GT acts as an authentic PBX IP and it can route the calls to/from a traditional PBX, Internet, LAN and PSTN. All that management is made by a software called Asterisk. Asterisk is compatible with the several signalling protocols, among which SIP.

The VoIP functionalities accessible through the web interface are next presented.
