Hi!

Please check the following link, specially Pg. 9 "ISDN/MGCP Cisco Fax Relay Mode" . You'll see the deployment models of the Cisco Fax server: IP T.38 Fax Relay, ISDN E1/T1 Direct Connection and ISDN/MGCP Cisco Fax Relay Mode:

*** Installation Guide Supplement for Cisco Fax Server ***

www.cisco.com/en/US/docs/voice_ip_comm/fax_server/90/faxigsup.pdf

Hope this helps!

Regards,

Teresa.

If it helps, please rate! :)

Hi Met,

Cisco fax relay is a proprietary fax method, and while Cisco Fax Server has the word Cisco in it, it is designed/maintained by RightFax. Thus, it does not support Cisco Fax Relay.

It's a legacy method anyhow, and T38 is much more preferred.

Thanks,

So can't I send faxes from FXS connected normal fax machines using fax relay in the gateways to the fax server?

Hi Met,

You can, you just use T38:

voice service voip

fax protocol t38 fallback none

The only restriction is you can't fax to SCCP controlled FXS ports. MGCP will have:

no mgcp fax t38 inhibit

mgcp package fxr

hth,

nick
