Hi everybody,

I have some problems with the dialog pings in OpenSIPS 1.10.
Most times dialog is working well but in some rare cases the dialog will hung.

E.g. this will happen if the BYE messages of both UAs were missed by the OpenSIPS server.

I'm using create_dialog( "pPB" ) to verify the dialog by the OpenSIPS server. In this case the server sends OPTIONS to both UA to verify the dialog.

If the OPTIONS request will be send inside the dialog the reply has a SDP body. If the call was already terminated for the UA the OPTIONS reply is also generated. The only difference is that the reply has no SDP body. In this case it checks only if the UAs are reachable and OpenSIPS will not destroy the dialog.

IMHO this looks very strange for me.
Does anybody has an idea to solve this problem?

Thanks in advance.

Regards
Bastian
