[Asterisk-Users] cdr issue

[Lim Han Shyong]

Dear all:

           hi,  i face some problem in the mysql cdr module. Here is my
situation, hope you all give some comments.

                            (cdr)
User ----------->   Asterisk         ------------------>          gateway
(IVR)  ----------------------->    (B party)
                                         (call access number)
(enter destination )



      For the case above, i try to use asterisk to bypass the gateway
process which mean asterisk dial the access and send dtmf to the gateway so
that the user no need to call the access number , they just need to enter
the destination number.

       It work fine, but i face problem for the cdr. The cdr is consider
"CONNECTED" when the gateway answer the call from asterisk. But what i need
is "CONNECTED" only if the B party is pick up the phone.

       Now the B party didnt pick up the phone, the call still consider
"CONNECTED" due to the gateway already answer the call from asterisk, and
even the B party pick up the phone, the duration still not accurate coz the
counter start count while the gateway answer the call but not counted while
the B party answer the call.

      So is there any way to solve this cdr issue or what i can do ? Please
kindly advise.

      I got one idea which is when the B party answer call, the gateway will
send the dtmf tone back to asterisk, then the asterisk can fire the
CONNECTED event,
 but i dont know how to do it in asterisk, please help..


Thanks in advance

Regards
HSL
