You can't control this in the dialplan. You control this by disabling 
T.38 support in sip.conf for that provider (setting 't38pt_updtl' to 
'no'). However, don't expect very high reliability transferring FAX over 
G.711 over the Internet.

Alternatively, if your provider claims to support T.38, then ensure you 
are running an updated version of Asterisk, and if you still can't make 
FAX work over T.38 with them, post debug logs here and we can try to 
help you figure why it's not working.
