No, unfortunately there isn't a way to do that that I can see. It <br />
wouldn't be terribly hard to add to res_fax.c, but I don't think we ever <br />
thought of doing that before.<br />

With out this I have no way to force the fall back then and the faxes will always fail in this case because t38 successfully negotiates.. Do you have any other ideas?<br />
If I pick arround in the source what might it take to add another option to the ReceiveFAX to only do g711 audio? Is this somthing that I could get submitted back into the tree if I can figure it out?<br />
<br />
Thanks<br />
