Hi Umar,
unfortunately I have not found a solution for my problem. I do not think that there is any problem in the dial plan. The IVR that I have is not done using asterisk. It is another application running on another machine with a telephony card (dialogic).
From my understanding, the presentation of caller id in between the firstand the seconds ring. That is why asterisk is waiting for 2 rings before picking up the call. For the same reason, I think asterisk is also sending out the caller id between the first and second ring to the phones. Hence, the caller have to wait for 4 rings before the IVR can pickup the phone with the caller id information.
The problem can be simulated using a caller id device. So instead of the IVR, the asterisk is connected to a caller id device. The caller will have to wait for 3 rings before someone answer the phone. Wait for 4 rings if we want to know who is calling.
I am wondering if there is any way or settings I can set to allow the caller id to pass thro' asterisk and let the IVR pickup the caller id information. This means that asterisk do not wait for 2 rings to process the call. Any ideas?
Thanks.
Regards, Chin

Hi Chin
Did you find a resolution, I could not see a response that solves your issue.
If you still have the issue it might be worth posting parts of your dialplan.
Generally speaking, I would change the IVR part of your dialplan so that it checks if caller ID has been set, in which case it answers straightaway, if not then it waits for two rings.
