[cisco-voip] H323 with PRI

Wed Apr 18 03:22:06 EDT 2007

Hello all;

I have a H323 gateway with one E1 PRI port, I have a callmanager ver 4.2. I want to configure outside calling to PSTN and inbound calling to IP Phones. for outside calling it worked normally I can call from IP Phones to outside and my correct caller ID is shown.

The problem when I am calling from outside to an IP Phone if I leave the E1 voice port with its dfault I got a dial tone when I call the number and if I dailed another extension number I can reach to this number. the alternative to this is to configure Connection plar 123 and all the calls to E1 is directed to that extension "123". I want when I call 6789123 i go to 123 extnsion and when I call 6789126 I go to 126, the normal operation for PRI as u know.
by the way it works  normally when configured as MGCP not H323. any ideas about this

here is the configuration:
