Dear sir/madam,

I am using A2billing for calling card purpose,now I would like to setup callback
The callback process will be:
1.Customer will call one of PSTN lines, which sends the caller ID 00252212131
2.wait until you get a busy signal
3.hangup
4.A2billing will make a callback to 00252212131 using one of DAHDI/g1
5. the caller will pick it up and will head dialtone
6.The caller will make an outbound call using one of my DAHDI/g1

Is that possible to implement using A2billing,I will apperciate if you send me any link.

Best regards,
Dayib
