Hello,
I want 'cid-prompt-callback'(it's newly added function) of A2billing work like, Get Callee number from caller by Asterisk dial plan function Read(caller_dtmf_variable|prepaid-enter-dest|20||1|8), not by AGI and get CallerId by CallerID function of dial plan, also not by AGI and if callerid is not present in a2billing database, it will ask for 'PIN NUMBER' which is has to be done by Asterisk dial plan function Read(caller_dtmf_variable|prepaid-enter-pin-number|20||1|8) not by AGI. After caller hungup, a agi will do the rest to spool the query into database for 'cid-prompt-callback' work.
Thanks
