Hi all, I'm looking into XTRN-419: MOH dialogs not terminated, where the Polycom fails to send BYE to sipXpark. I am not able to reproduce this on my system.
One thing I notice in the attached 5dd1870e-d761efbb-7b9706bc.xml siptrace is that sipXpark sends three separate OPTIONS requests to the Polycom in the MOH dialog. That doesn't happen in my system, and is probably has something to do with why my Polycom correctly sends the BYE. I understand that this is legal for sipXpark to send the OPTIONS requests. But I don't understand why it would need to do this at all, since the options being queried are all advertised in the INVITE. I also don't understand why it sends the second and third OPTIONS requests, since it got an answer the first time. Can anyone tell me why sipXpark does this, and under what conditions? Thanks. -Paul [email protected]
