FAX over Asterisk

Asterisk Asterisk Support
1

I am (still) trying to get FAX to work. I am using SIP protocol and the NVFaxDetect operation. I kno wthat the SIP service transmits fax codes and I am using alaw/ulaw.

I am currently stuck on:
…
2006-10-23 12:51:54 NOTICE[31513]: Redirecting SIP/gw02.uk.sipgate.net-408af0a0 to fax extension
2006-10-23 12:51:54 WARNING[31513]: Context
2006-10-23 12:51:54 WARNING[31513]: Fax detected, but no fax extension

As far as i can tell there is a fax extension, and the setup is very similar to the example in the documentation.

Where do I look next?

Similar to what documentaion?

and as far as you can tell you have a fax extension, perhaps if we could see the code we may also be able to see if you have one ?
