t.37 onramp fax

I am attempting to get t.37 (and eventually fax detection) working on a 2811. Currently testing with FXO and FXS ports it seems like the IVR script errors out.

We have tried both incoming over PSTN to the FXO port, and then generating from a fax machine connected directly to the FXS, but both times after the fax signal is sent it retires and errors out.. any thoughts?

Here is the applicable config and debugs:

application

service rollover flash:fax_rollover_on_busy.2.0.0.tcl

!

service faxmail_onramp flash:app_faxmail_onramp.2.0.1.3.tcl

param accounting-list fax

param authen-list fax

param authen-method gateway

!

service fax_detect flash:app_fax_detect.2.1.2.2.tcl

param account-id-method ani

param mode listen_first

param prompt flash:en_listen_first.au

Re: t.37 onramp fax

It's probably never getting a called number on the FXO port. You could use a translation pattern to give it one. Example:

!

voice translation-rule 1

rule 1 /^$/ /7777/

!

!

voice translation-profile DNIS-Replace

translate called 1

!

!

...

voice-port 1/0/2

translation-profile incoming DNIS-Replace

...

!

dial-peer voice 26 mmoip

application fax_on_vfc_onramp_app out-bound

destination-pattern 7777

information-type fax

session target mailto:inboundfax@test.com

...

dial-peer voice 25 pots

application onramp-fax

incoming called-number 7777

direct-inward-dial

port 1/0/2
