[SIPForum-discussion] Parallel forking behavior

[Sam Kirubakaran L]

Hi,



I have some doubts regrading parallel forking of INVITE request.


Suppose I have 3 contacts registered to the location service and while forking, proxy forwards the INVITE to 3 UASs.


Consider the UASs are A, B and C.


And A's 180 response is the first to reach the proxy which will be forwarded to UAC. And also the proxy had received the 180 response from UAS B and C.


What if B sends 200 OK before A? How the proxy will process the dialog state ? What will be the behavior of the UAC ?


Regards,

Sam
