We implented a new virtual fax server and it's connected to my VG2911 with an H.323 connection between the fax server and gateway.
Faxes from the east coast are fine but when offices from my west coast offices fax I see the call connect to the fax server but then it gets dropped.
Is there anything specific I can look for?
Thanks,
Mike

Do you have your GW configured for T.38? Are you using protocol based or NSE based T.38?
Can you post relevant config?
What if you call it do you get fax tones?

OK, so you are using protocol based, good.
Why is session target on your voip dial peer blank? This does not point to anything. You need to point it to your fax server's IP address.

I removed them..
I have them in my actual config... I have faxes working but I have problems when faxes come in from the west coast to the east coast. I see the call connect on the VG and connect on the fax server but then it times out and the west coast offices get an erro message that states "poor line connection"

Where are the west coast faxes come in to? Are they coming into another GW and then are sent to this one?
Can you post config of that GW as well as "sh controller T1" from both?

My fax server resides in NJ. All faxes come into NJ and then get sent via email. They come directly to this gateway there is nothing inbetween.
