Re: Fax Machine - FXS Port issue

Which protocol are you running on the E1?

Also check "show controllers E1" for slips and if any configure networck-clock-participate and -select.

Hope this helps, please rate post if it does!

Hi, I had the same thing regarding ringback for incoming calls:

It would work when calling from a fixed line, but not from my mobile

Once I have configured "voice call send-alert", ringback worked also for mobile calls.

HTH (at least for the ringback portion of your problem)

We had a similar problem with our VG224 gateways. When we updated the IOS to version 12.4(15)T1 the problems went away.

Thank David,

I was having the ringback problem, and it is gone after I configured "voice call send-alert".
