Failed Faxes

Unanswered Question
Oct 14th, 2009

We have a legacy PBX which our analog fax lines are located. All calls made from a fax machine or received enter and exit through our Cisco 2821 Router. We are getting alot of failed outgoing faxes. Can someone suggest something we need to do, possibly reprogramming the router??

Thank You

I have this problem too.

Configure:

network clock/participate wic 1

network-clock-select 1 t1 1/1

controller t1 1/0/0

clock source internal

And check for slips stopping or increasing.

Mojo1 Wed, 10/14/2009 - 12:01

I tried these settings. The first 2 were already in there.

When I adjusted the clock source to internal for the long distance t1, the errors increased. I have moved it back to a clock source of line. The errors have slowed down, but are still slipping.

Paolo Bevilacqua Wed, 10/14/2009 - 13:58

Not sure if you configured the right controller or not.

I meant, change clock source internal under controller going to PBX, not long distance.
