I have a Cisco Voice Gateway 4331 that handles all of our calls in conjunction with Cisco Call Manager. The voice gateway has a PRI circuit connected to a port and three POTS lines using the remaining three ports. In this example, I want to have the internal extension 3337 use the specific port of a POTS line on port 0/2/2. This is for a fax machine (attached to CUCM via an ATA 190) that only sends and I am having trouble with it being reliable over the PRI. I was hoping to tie it to a POTS line to avoid trouble.
I tried the following and it did not seem to work correctly. I feel like I am missing an important component:
dial-peer voice 3199 pots
desc ***** Send faxes over pots lines for mailroom *****
In the above, I am attempting to identify the internal extension of the fax machine (3337) so that it can be directed to use the POTS line on port 0/2/2. Is there another set of commands that I might be missing?
