Right here goes, inbound faxing is working great, I have a fax server GFI Faxmaker running a Brooktrout SR140 FOIP boardless driver. Outbound faxing fails every time. Here is the config of the 2651XM router: -

Attached are 2 files with ISDN q931 debug and DialPeer debugs
file 1 is a CSIM start that works, file 2 is a call originating from the FAX server that fails. I think it is a signalling issue but don't know where the responsibility lies to fix it, is it GFI/Cantata or Cisco or PSTN service provider?
Any help would be great, do I need to use a h323 gatekeeper? I really do not know what is causing the problem.
Cheers

Fax pass-through is supported under the following call-control protocols:
⢠H.323
⢠Session Initiation Protocol (SIP)
⢠Media Gateway Control Protocol (MGCP)

I have resolved this issue, the fax server was forcing all calls out to the PSTN as ISDN National, so the PSTN was not understanding the numbers dialed. I added ISDN maps to map the dialed numbers to National or international and changed my dial-peers to only send national and international numbers without prefix codes i.e drop the prefix '0' for national and prefix '00' for international and prefix local numbers with '1624' for local isle of man dialing.
