Hi all,
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.
To overcome about this, I'm searching for a way to
force SER to delete an
"old Contact" when a Registration is done with same URI and different IP;
That way, only one Contact for one URI is available. I've tried to add
modparam("registrar", "append_branches", 0) in ser.cfg, but in this
case,
Contact with lowest 'expires' parameter is called, and not Contact with
highest one, still causing confusion fo IP calls.
The proper parameter is:
modparam("registrar", "desc_time_order", 1)
