[cisco-voip] ata issue

[Scott Voll]

Need a little more info.

is RTP packets going across the WAN via G729?  This would be a problem
change to G711.

are all your Faxes, just dumb faxes?  eg. they only fax at 14.4k?  or can
they fax Super G3 33.6k?  might be a trying to fax at 33.6 if the other fax
supports it.  Work around turn off Super G3 on all your Fax machines and
also turn off Error correction Mode (ECM)

do you have a VGW set to Fax Relay?  all VGW should be set to Fax
passthrough.

hope that helps

Scott
