[OpenSIPS-Users] Identify CDR accounting on dialog-timeout

[Razvan Crainea]

Hello, Jayesh!

You can not achieve this scenario in OpenSIPS 1.7.1, but you can wit the 
acc module from trunk version. There you have a new parameter, 
db_extra_bye[1], that can evaluate the pseudo variables after the BYE 
message is received.

An easier way to implement this, is to initialize a dlg_val with the 
value 1, and if you receive a BYE message, change it to 0. If you don't 
receive any BYE and a timeout is triggered, then the value will remain 1 
and that is what you will see in the database. Otherwise, for a normal 
hang up, you should set it to 0 and this will  reflect in the DB. But 
once again, this will only work with the trunk version, adding the 
dlg_val to the db_extra_bye parameter.
