[cisco-voip] Fax Server

[Turpin, Mark]

In my experience with Rightfax, I set it up using the brooktrout t1 card (although IP was touted as being easier, I didn't think so).  It was connected to a 6500 with a cmm/pa-6t1 (but any pri supporting router will do) and the brooktrout.  We were doing pass through (not relay), and everything worked like a champ once we got the circuit up.
 
Just ignore what they're saying about MGCP and fax relay, you don't have to do relay.
 
By the way, I used 4ess, network side, and internal clock for the 6500 side of the t1.  We couldn't get it up with the 6500 being the customer side.
 
Brooktrout has excellent customer support, too.

I'm doing my first Fax Server install (Rightfax) version 9.0, and I looking for some guidance. According to the Installation Guide Supplement for Cisco Fax server, there are three deployment methods. 

 

IP T.38 Fax Relay

All traffic to brooktrout card is via IP. The T1 interface is not used. The Ethernet on the MCS server uses SIP for call control, and the Ethernet port on the Brooktrout card is used for media (FOIP UDP packets). - H.323 must be used on router.

 

ISDN E1/T1 Direct. 

T1 connects directly to T1 port on Brooktrout card.

 

ISDN/MGCP Cisco Fax Relay Mode

Used where mixed voice and fax traffic share same trunk and uses ISDN overlap sending for signaling. When deployed in this mode, all fax traffic to the fax server uses the Brooktrout card ISDN interface. Call signaling for the fax call setup will first traverse the Callmanager using MGCP. For this configuration either an additional ISDN interface is required on the router and this plugs directly into the T1 interface on the Brooktrout card.

 

My router is currently using MGCP, so to me the last model looks like the way to go, but most the document refers to E1 versus T1, and I'm not sure about the ISDN overlap signaling.

 

Can anyone offer any advice on the best way to proceed?
