I've configured a local SER on our network, and I met some difficulties with multiple Contacts. When UA1 changes IP address, and REGISTER in SER to announce his new IP, both last and New Contacts are placed in Location table, with different 'expires' values. If UA2 receives last UA1 IP address, and REGISTER with it, calling UA1 from UA3 when both Contact still available, makes UA2 ringing, which cause some confusion.
That's a fault of the UA. The UA should un-REGISTER the old contact before registering a new one.
Not necessarily. For instance consider UA1 and UA2 are identical UAs on different DSL lines. They get dynamic IP. The DSLAM reboots. Lines come back up slowly. If ser gets a valid register request for UA1, it seems to me it should remove all trace of the old IP address ASAP, as "I am here" rather implies "I am not there (where there != here)".
It depends - if I have a SIP phone on my desk and a softphone on my notebook, booth should be registered and reachable.
