I did find the same problem from another user on the list in the archives, but didn't find a solution contained within the responses [2].<br><br>Thank you,<br><br>--Tim<span name="x"></span><br><br>[1] https://wiki.asterisk.org/wiki/display/AST/T.38+Fax+Gateway<br>[2] http://lists.digium.com/pipermail/asterisk-users/2012-July/273535.html<br></div></body></html>
