I am using asterisk 1.4.19 & have recently installed a2billing 1.6. I want to use it for conference services on asterisk.

I route my Zap call with DeadAGI(a2billing.php|1|callback).

From Callback it goes to Local/918301@from-internal & it comes back to extension.conf - context: from-internal; extension 918301 which also is the conference room no.

I want to know the Originating Zap channel number, after the call comes back from AGI to extension 918301.But the asterisk channel variable ${channel} now have the value "Local/918301@from-internal-35f5,2. which is the Local Channel.

Please tell me how do I capture the Original ZAP Channel number?
