SIP Development

Session Initiation Protocol (SIP) is the popular signaling protocol for originating and controlling VoIP (Voice over IP) calls. In addition to providing the mechanics for setting up and tearing down a call, SIP enables video conferencing, streaming multimedia distribution, instant messaging, presence information, file transfer, and fax over IP.

From calling between two office phones, to connecting users in different parts of the world, SIP is the protocol behind almost all of the tools Lintel uses in developing telephony products.
