Hi Tom,
I am assuming that you are going to use the FXS ports on the UC540. If so, you have 2 options. You can configure the FXS ports as H323 or as SCCP. If you are going to use H323, you will just need to configure a dial-peer pointing to the FXS port that your fax is plugged into. Example:
dial-peer voice 1 pots
description Incoming dial peer from PRI
incoming called-number .
port x/x/x:23
direct-inward-dial
dial-peer voice 2 pots
description Analog Fax
destination-pattern XXXX
port x/x/x (FXS Port)
If you are going to use SCCP, you will need to configure the SCCP FXS ports, ephone-dn, and an ephone. Here is basic config you will need to have:
stcapp ccm group 1
stcapp
!
!
!
!
sccp local [interface you want to bind SCCP signaling to]
sccp ccm x.x.x.x [CME IP address] identifier 1 version [CME version]4
sccp
!
!
sccp ccm group 1
bind interface [interface you want to bind SCCP to]
associate ccm 1 priority 1

dial-peer voice 1 pots
description Incoming dial-peer from PRI
incoming called-number .
port x/x/x:23
direct-inward-dial

dial-peer voice 2 pots
description FAX
service stcapp
port x/x/x

ephone-dn 1
description FAX
number XXXX
name FAX

ephone 1
mac-address xxxx.xxxx.xxxx

Hope that helped.
