[OpenSER-Users] proper call tear down

[Ovidiu Sas]

Hi Miles,

One option would be to build something on top of the existing dialog
module (an in-dialog OPTIONS pinger) that will ping each participant.
As soon as one participant is not responding, the call can be
disconnected with a proper EDR.
Maybe an item for 1.4.


Regards,
Ovidiu Sas
