To all your gateway gurus... 
 Brooktrout t38 Fax Board w/ RightFax to Cisco Call Manager (4.1)
 Has anyone done one of these?
 Im in a situation where my customer is wanting to implement this. However 
all Brooktrout has to offer in the way of support is whitepaper with a 
sample configuration for an h323 gateway.

 My customer setup is MGCP so i'm a bit puzzled on how to accomplish this.
 What we are wanting to do is take a few DID's and forward calls coming in 
on them to the fax server.
 Rightfax and Brooktrout tell me that I need to point the fax calls to the 
IP address of the fax server with something similar to this:
 ==============
voice service voip
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none
sip
 voice class codec 1
codec preference 1 g711ulaw
 dial-peer voice 78197214 voip
description Used to receive a fax comming in the T1 ISDN line, which is 
781-972-1400 (DNIS = 1400 - 1499)
destination-pattern 14..
voice-class codec 1
session protocol sipv2
session target ipv4:10.128.31.64 <http://10.128.31.64>
session transport udp
==============
 But since I am using MGCP is there any other way to accomplish the same 
thing?
 Also, the mgcp fax t38 inhibit I would imagine need to be turned off, but 
this is what makes my analog fax relay to my ata188's work...
