I have a 3725 running CME 3.1 with a fax machine connected to an FXS port. Since the upgrade from CME 3.0 to 3.1 I have been unable to send faxes. Fax machine gives a communication error. It dials and starts the connection to the destination fax then fails.
Here are excerpts from the config. The only thing that changed was the CME to 3.1 and the IOS to 12.3.7-T to support CME 3.1
Calls come in on a T1 PRI

Try this configuration on both ends, it fixed a number of fax issues we ran into...
