VG204 Unable to Fax. States line is busy.

Question

Hi,
I have an extension on a VG204 port that when you try and fax from it or to it it fails. If you plug an analogue phone into the port you can make and receive calls so it is not a routing issue, this all appears to be normal. When you dial the number you get the fax tone but if you try to fax it, the fax fails.
I have disabled T38 in case this had any issues with it. I have also asked them to make sure the speed is confirmed as 9600 on the fax. The fax machine works when you move it to another GW (unfortunately a different GW as this is the only fax in that location). And when you move a working fax to that port it also fails.
Any useful suggestions?!
The only things I havent tried are cabling replacements.
