[Asterisk-Users] Caller id and the number of rings

[HengWee Chin]

Hi all,

   I have the following setup
   PSTN -> ASTERISK -> IVR (using dialogic card)

1) Caller id information is presented to asterisk during the first and 
second ring.
2) Hence, Asterisk waits for 2 rings before pickup the call and forwarding 
to the appropriate FXS port.
3) The IVR application also waits for 2 rings before picking up the call to 
get the caller id.
4) Hence any caller calling to the IVR will have to wait for 4 rings before 
he is serviced. This is too long.
5) Anyone have any idea how can I reduced the number of rings and still have 
caller id available to IVR?
6) If I were to switch PRI ISDN, would I still have the same problem?

Thanks in advanced.

Regards,
Chin
