Cisco ATA 188

I have the following problem :

We fax 5 page doc and then ATA 188 is not responding ? The green led on the back is on, the red light on the top bottom doesn't go on, it is visible on the network, and it responds to a ping.

This is what I got doing some read on Cisco's site :

"A hardware replacement is probably needed. Open a case with Cisco Technical Support."

We replace a ATA 188 almost every two weeks. We running CCM 3.3.4 with Service Release 1 and ES 49

Any suggestions ?


Re: Cisco ATA 188

To resolve this problem, try to modify these parameters:

Change the fax speed to 9600 bps (the recommended speed for no issues).

Set the protcol to G3.

Disable the Error Correcting Mode (ECM).

If the other actions mentioned do not work, plug the fax machine into the Foreign Exchange Station (FXS) port in the router and configure the router for modem pass-through.

If none of these workarounds is successful, a different fax machine must be used.
