Dear All:
I have one question to ask, the situation is listed
as the following:
User A call User B via Proxy P, User B has three
contact address in the registrar whose domain is the
same as that of the proxy P. So when User A send
INVITE request to User B, this INVITE request will be
forked into three branches,the INVITE request will
reached User B(1),B(2),B(3). the demonstration diagram
is listed as the following:
B(1)
A---- P -------B(2)
B(3)
When B(1) receives INVITE request, without sending
100 response, B(1) sends BYE request to this INVITE
requst, when this request arrives P, according to the
CallLeg, it can match, then what would Proxy P do?
Wait for other B(2),B(3)'s response? Or delete the
corresponding State machine in P? or throw this BYE
request?
My opinion is that P waits for other response,
after definitive time, for example, if receives 200
response and 400 response, then 200 respose will be
sent to A, and the state machine for BYE and 400 will
entered into corresponding state.
Could any one give me some suggestion or idea? any
suggestions and ideas are welcome!
I am looking forwards to getting your reply as soon
as possible!
Best Regards!
Yours: James
