[OpenSIPS-Users] Dialog ping question

[Bogdan-Andrei Iancu]

Hi MS,

You can use the Call-ID to correlate with the dialog. For example, use 
the localcache to store (when creating the dialog) a record having as 
key the call-id of the call and as value the time to start. In the 
generic on_reply you can look for that records into localcache and to 
the math for the duration.

Regards,
