We have a Pitney Bowes mail machine that connects via a modem to a location to load mail data. It has worked fine for years on an analog port using a VG248 and CallManager 6.1 About 3 weeks ago we upgraded our voice gateways to use Cisco 2911 devices and since then the mail modem doesn't seem to work. It works fine on a POTS line but when we try to use it on the Analog port, the modem dials and sounds like it's trying to connect but never does. Voice calls work fine on this port.
Any ideas on where to look?
