SIP stack for NGN networks

Netbricks SIP stack called SIP-BRICKS™ is a source code implementation of the Session Initiation Protocol suite as laid down by the IETF Transport Working Group. Our SIP stack is fully compliant with IETF SIP RFC 3261 (core SIP), RFC 3263 (Locating SIP Servers) and RFC 3264 (An Offer/Answer Model with SDP) (they obsolete RFC 2543 published in March 1999) and SDP RFC 4566 . An IMS SIP version compliant with "3GPP IMS" and "ETSI TISPAN" documents is also available.

The SIP protocol is a description and signaling protocol used to describe, establish, modify and terminate multimedia sessions or calls. SIP uses an IP network to transport the signaling messages through UDP, TCP or SCTP (please refer to RFC4168).
