I have CME 4.1(0) running Cisco 2811 router with 4FXO cards and want to connect it to Siemens PBX. I have configured pots dial-peer for PBX with destination-pattern 1.. as PBX has extensions of 1xx. Here i am faciming couple of issues.

1. From IP Phone when i dial a valid extension, i.e. 129 it gives re-order tone. But when i tried 1129 (assuming that router is skipping first digit) the Analog phone at PBX got connected. But there are times that when i dial 1129 at IP Phone (ip communicator) it takes 112 extension discarding the last digit.

Can anyone tell how to resolve these issues.

2. Can i create a hunt group for 4FXO ports so that call can hunt on these ports.
