[cisco-voip] Brooktrout t38 Fax Board with Cisco Call Manager

[Wes Sisk]

Hi Nick,

CM does not support T.38 yet, so your only option is to use an IOS h323
gateway as the PSTN gateway or dedicate a few CO lines on an alternate PSTN
gateway.

It is in the works for CM to do t.38.

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
 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...
