[OpenSER-Users] How to account INVITEs and not "200 OK"s?

[Bogdan-Andrei Iancu]

Hi Peter,

First, if you start accounting when the INVITE comes in, you charge the 
user for the time while the phone rings...?!? :D..

Secondly, for redirect scenarios, see in ACC module, the multi-leg 
section. It is what you are looking for.

Regards,
Bogdan
