I have a CUCM 8.6 setup at my main site. We are moving one of my remote locations and right now we have a dedicated POTS line just for a fax machine which I was hoping to get rid of. The remote site has a Cisco router which is a H323 gateway with a PRI going into it. Anyone have any idea how I can port my POTS number into the PRI and get my physical fax machine to communicate with the router for faxing passthrough? It looks like the Cisco ATA 187 might be used to do this?
