Dear all,

I encountered a problem on the dial peer. The situation is that we have IPCC deployed and C2811 deployed as the voice gateway.

C2811 has a E1 interface card to link to the PSTN, and has a main number for our customer to call in. The problem is that we need to match the different route script on ICM for the different area customer who call the main number.

So on C2811 can I match the dial-peer according the calling number for the incoming call, because the called number is same. after matching the specific dial peer I can translate the called number to the different Route point number for ICM .

The principle is the same: answer-address matches ANI.

Use answer-address on the incoming pots DP for that. You can use also patterns then achieve what you describe above.

Basically, calling number routing.

thanks bevilacqua,

But I can't fully understand what you told me.

what is the "answer-address" command used for? I think this command is working after the call match the dial peer.

And how can i enable the calling number routing?

When a call coming from the PSTN with the same called number and different calling number, how can i match the call session to the different dial-peer according to the calling number.

Could you give the instruction?

Thanks very much.
