[cisco-voip] Fax Server

[Gary L. Pate]

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?
