Hi Benny,
Thanks for you help in advance.
Sorry for the unclear information I provided before.
(1) The event ID does exist at out dialog SUBSCRIBEs only. I'm not sure if this is a problem for the scenario we mentioned before.
All the trouble I said before was in dialog KPML and REFER.
(2) The code flow that what I seen was
a. In dialog KPML was received.
evsub0x1003d1a UAS subscription created, using dialog dlg0x10039eb4
b. dlgsub belongs this KPML was allocated by evsub_create()
==== [on_new_transaction()] Subscription lookup info dlg=0x10039eb4 dlgsub=0x1003d564 -----------> Here I dumped the dlgsub instance at on_new_transaction()
c. User transfer the call
evsub0x1003ae8 UAC subscription created, using dialog dlg0x10039eb4
d. A brend new dlgsub was create for this REFER also by evsub_create()
===== [on_new_transaction()] Subscription lookup info dlg=0x10039eb4 dlgsub=0x1004f9f8 -----------> Here I dumped the dlgsub instance at on_new_transaction()
I don't see the 2nd dlgsub (REFER) attached to the 1st dlgsub (KPML). ???
e. Receive the expires=0 KPML packet
====== [on_new_transaction()] Subscription lookup info dlg=0x10039eb4 dlgsub=0x1004f9f8 ------------> The dlgsub list contain the REFER method only.
Subscription Does Not Exist for SUBSCRIBE, event=kpml;id=
Please give me more insight regard this, thanks for your help in advance.
Best Regards!
The roughly packet header FYI..
