oSIP implements the Session Initiation Protocol (published by IETF as RFC 3261). It can provide signalling capabilities for multimedia applications (IP phones, etc.). It provides a fully usable parser for the SIP syntax and implements the "transaction layer" as defined in the draft. It also provides an SDP parser and extra features for the User Agent. It can be used to build both proxy and IP phones.
