Interoperability
From Snom User Wiki
Overview
snom VoIP phones use the SIP protocol according to RFC 3261. Therefore our interoperability support for third party SIP Public Branch Exchanges (PBX) is limited to the basic functionality defined there as the "five facets of establishing and terminating multimedia communications:
- User location: determination of the end system to be used for communication;
- User availability: determination of the willingness of the called party to engage in communications;
- User capabilities: determination of the media and media parameters to be used;
- Session setup: "ringing", establishment of session parameters at both called and calling party;
- Session management: including transfer and termination of sessions, modifying session parameters, and invoking services."
