For some reason our fax machine will only recieve a fax and no ling send. I know its an issue with the CM and not the fax machine. If I plug the RJ 11 inot the port beside it it will send a fax and not receive. Anyone know what that is?

Commented:
actually you have to connect your fax machine to FXS port so based on that we will configure it but what do you mean by two ports??

I am sending you a picture. It has an FXS car in it but there are two ports. The RJ11 for the fax is the white cable in the middle. Its going to the left port. The cable is in the FXS card.

Im not sure what the IP address is. I went into the interface on the switch and can see that the 2811 is comin goff of port 7 but I can seem ti find out what the IP is. I will see about consoling in and getting the show run.

Called Cisco and put in a TAC request. An engineer came in and saw thatthe timin gwas not in sync with the PRI. He adjusted the time and now it works fine. Thanks for the help.
