Thanks for the tip. Sadly, it didn't work. I keep getting the same error:<br><br>[Mar 10 18:49:48] WARNING[18855]: app_fax.c:176 phase_e_handler: Error transmitting fax. result=11: Far end cannot receive at the resolution of the image.<br>

</div>I think, that at least if you're using T.38, you may want to try<br>
enabling ECM. ECM can cause significant problems in a high-packet loss,<br>
non-T.38 environment, but I would think that in a T.38 environment, if<br>
you can keep ECM enabled, that would be a good thing.<br>
