[cisco-voip] Fax debuging?

[Sean Watkins]

Hi,

I have an interesting problem. I have a specific carrier that I connect
via PRI which on cisco eqpt or another vendors TDMoIP gear, cannot seem
to pass any faxes. 

Phone calls complete succesfully, but faxes no. Faxes to other carriers
on the same eqpt (either cisco or TDMoIP) work ok. So, its pretty much
something in particular with this carrier.


Any suggestions? In talking to the carrier they are not doing anything
funky but I am at a loss as to why faxes do not complete on that
specific carrier. They are the typical carrier where of course nothing
is their problem ...


I've checked ----

	1) Clean T1s
	2) Good Timing
	3) Verified the Cisco gear works as I get the same problems on
another piece of eqpt

	
What else is there to check? Is there any fax diagnostics box I can get?

Any  suggestions short of firing this carrier?
