Re: FAX over E1 Pr1 line problem

hi Bruno,

Hope you might have already fixed it.

you can do two things,

I am assume that FXS port connected to CUCM as MGCP.

1. This scenario CUCM will decide the routing the calls through CSS what is built on DP.

2. Take a simple analog phone connect to FXS line and make sure you have both incoming / outgoing if that works fine I expect it to work fine.

3. Check for t.38 or Modem Pass-through enabled on the GW or CUCM GW page.
