Hi, I have A2Billing 1.8.5

I have the following in extensions_a2billing.conf

[a2billing-callback]
exten => _X.,1,DeadAgi(a2billing.php|1|callback)
exten => _X.,n,Hangup

Also in extensions_custom.conf

[custom-a2billing-callback]
exten => _X.,1,DeadAgi(a2billing.php|7|callback)
exten => _X.,n,Hangup

In a2Billing system settings/callback group, I have
context_callback=custom-a2billing-callback

If I understand right, for the A-Leg (Callback Leg) of the call, because I have context_callback=custom-a2billing-callback,
the callback deamon will use agi_conf7 instead of agi-conf1 as in the [a2billing-callback] context, hence [a2billing-callback] will not be used. On the other hand, the B-Leg of the call is just another voip call, and is being handled by [a2billing] in extensions_a2billing.conf.

Hence, to modify how Web Callback is done, I just need to modify agi_conf7 according to the setup described above.

Please confirm, anyone ....
Thanks.

In Web Callback, once a callback request is received, the daemon will outbound
the call to asterisk and redirect it on the context defined in the setting "context_callback"

So in your case it will use :
[custom-a2billing-callback]
exten => _X.,1,DeadAgi(a2billing.php|7|callback)
exten => _X.,n,Hangup

therefore, the agi-conf 7 will be used for the configuration...

Thanks Areski,

Works beautifully, including the CallerID's on the A-Leg (I use PD Caller ID for the callback leg, otherwise A-Number gets whatever the VOIP provider sends) and the B-Party gets the Caller's CallerID (I have auto_setcallerid=YES and cid_sanitize=CID).

Suggestion: Wouldn't it be more practical that the B-Party sees whatever the A-Number enters as CallerID? At least as an option in the conf file (jOption: Just use whatever the A-Number is for CallerID)

Example scenario:

The customer is in a place where he/she has access to a fixed phone that does not belong to her. She gives that number as A-Number, and enters the number to call to the B-Number.

The called party sees whatever the caller has in her CallerID/DID list (and actually randomly if he/she has more than one).

Called party cannot answer the phone, but tries to return the call (by calling the number on the CallerID received) and the A-Party is not there.

Keep up with the good work!
