VoIP enabled PBX systems (or IP PBX) is low cost for business voip solutions as updates are done through softwares and not hardware.
Inter-Asterisk eXchange (IAX) is a protocol used by Asterisk. Asterisk is an open source Private Branch Exchange (PBX) system from Digium. IAX is now known as IAX2, with its second version. It enables VoIP connections between Asterisk servers and IAX2 clients. Even though IAX2 is not an official standard protocol, as yet, it is well known for its less bandwidth consumption. IAX2 uses in-bound data streams i.e. both signaling and media information are transmitted by the same channel. Whereas, in SIP and H.323 both signaling and media are independent of each other. That makes IAX2 NAT friendly protocol. However, that implies that the PBX needs to separate voice from signaling. IAX2 "trunking" allows one IP packet to contain information for more than one active call. Thus minimizes the use of bandwidth.
