[cisco-voip] fax and data using 4fxs/did

Hi folks,

 

We recently installed a CCM+Unity system.  It works great in just about
every respect.  We also put a 4fxs/did card in the 2651xm for analog
applications, namely modem and fax.  While I can make and receive calls
using an analog phone over these lines, data transmissions receive lots
of CRC errors and faxes get only partially transmitted.  

 

I know enough about this system to manage CCM and Unity using the web
interfaces, and I know enough IOS to bring up simple t1 links for data.
This IPT stuff is all new for me.  I would really appreciate some help
in diagnosing this issue.  I can provide whatever information you all
might need to help.

 

It seems like I might need some additional configuration here:

 

voice-port 1/0/0

!

voice-port 1/0/1

!

voice-port 1/0/2

!

voice-port 1/0/3

!

 

These, I believe, are the 4 ports from the 4fxs/did.  They're all fax
and data.

 

Many, many thanks,

Jeremy
