Somehow we need and indication, that the call that is showing up on (e.g.) the mobile phone, is redirected from the PBX.
Normally when you redirect one of these codes: http://www.voip-info.org/wiki/view/SIP+Response+class3
are included in the direction info.
This means, if I call the cell directly on its own number A-numbers will be displayed "XXXXXXXX" BUT if the call i redirected to the cell phone, the A-number will (do to the codes mentioned above) be displayed "-->XXXXXXXX"
Then you are aware that you (with the cell phone) is paying for the redirection.
So far we have been tracing in the files, but can not see any indication in the files, when a call is redirected.
I hope the above made it more clear, so any ideas??
