Hi.

 Thats what I do and have not had a problem, we only do maybe 10-20 
faxes a week though.
I set my channel variables in a macro and then goto a context receivefax 
where I enter on s,1,Rx.Fax , on hangup I do the actual mailing and 
sending of the fax. Before the sending though I make sure the fax 
actually exists.
