Some casees in whicih the UA should send a PUBLISH: a) The device is started so it automatically publishes "online" status. b) An existing publication is about to expire, so the UA automatically refreshes it by sending a new PUBLISH with "SIP-If-Match" header. c) The human user explicitly wants to change his status to "busy" so the UA sends a PUBLISH. IMHO it's not so hard to understand these cases. It's more or less obvious. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
