Hello,
I'm currently experimenting with OpenSER 1.2.0 with Presence module. Earlier I tried OpenSER 1.0/1.1 with PA. I'm using a third-party softphone which for some reasons, I would not like to disclose the name of it.
After switching to 1.2.0+Presence, the softphone segfaults on startup. After tracing the source code of the phone and OpenSER and performing hundreds of packet sniffing over the past several days, I have grown to suspect that a certain behaviour with the new presence module may be the cause, but I would like to verify whether that is the case.
For some reasons it is infeasible for me to modify the source code of the softphone used (actually I may be able to but that is what I would like to avoid). But it seems to choke on receiving a NOTIFY before the OK for the corresponding SUBSCRIBE is received by the softphone.
So, any chance that I can test it by just modifying the config of OpenSER alone without changing the sources, both of OpenSER and the softphone?
Thanks in advance for any invaluable insights.
Regards, Bernard Chan.
Hello,
the NOTIFY should be sent after the 200OK of SUBSCRIBE, otherwise the dialog is not created in client side. However the UA should not crash but send 481 "*Call Leg*/*Transaction* Does Not Exist".
Do you see the NOTIFY leaving from openser before the 200OK? Could you send a network capture with timestamps?
Cheers, Daniel
