it means that your sender is capable of sending t38, but asterisk (without at 
a minimum the t38-patches for passthrough) is not capable of handling this. 
if you have reinvite for this channel allowed and your sender can send the 
fax over g711 asterisk will send a reinvite and the fax has a chance of 
getting through.

afaik the warning is not an issue if you and your sender can reinvite to g711.

greetings from graz,
