hi,


I have a CUCM and have ip phones and ata (fax machines) registered to it. I want that call initiated from phone users will chose the PRI for outside calls, While the Fax machines calls/faxes go through the FXO lines (both lines (PRI and FXO) are terminted on the same gateway).. the gateway is communicating with the cucm via h323. Now the configuration for this need to be done on gateway.. Kindly suggest how it will be configured..



Regards

Hi


Since you are running H323, you can do it via cor list on gateway. Here is a sample configuration.


Lets say your Phone ranges 4xxx, and ATA number is 4205



dial-peer cor custom

name ata

name phone

!


dial-peer cor list ata

  member ata

!

dial-peer cor list phone

member phone

!


dial-peer voice 1 voip

answer-address 4...

corlist incoming phone

codec g711ulaw

dtmf-relay h245-alpha

!

dial-peer voice 2 pots

destination-pattern 9T

port 1/0:23

corlist outgoing phone

!




dial-peer voice 3 voip

answer-address 4205

corlist  incoming ata

codec g711ulaw

dtmf-relay h245-alpha

!

dial-peer  voice 4 pots

destination-pattern 9T

port 0/1/1

corlist  outgoing ata

!



you may need to change the answer address if you are sending 10 digit calling nubmer or not. Also, destination-pattern whether you are sending 9 or not


But the idea behind is, based on calling number, it will match incoming number and restrict the outgoing dial-peer


Hope this helps. commands may be slightly different then what actually is, cause I'm writing from memory, no router in front me now


Thanks
