<p class=MsoNormal><font face=Arial size=2><span style='font-size:10.0pt;
font-family:Arial'>Is there a built-in way of detecting fax tones, or a switch
to T.38 on a SIP channel? I need to periodically check some efax servers for availability
and figured the best way to ensure they are operational is to check for tones.
I’ve looked into Nvdetect but the company seems to have gone out of
business and I don’t want to be stuck with a solution that won’t
make it through an upgrade of asterisk. My ITSP supports T.38 and should send a
Re-Invite so is there a way to just set a channel variable when it sees this
and use that as an indicator of success?<o:p></o:p></span></font></p>

have any T1/E1 connections, so unless I’m mistaken I can’t use the
fax detection in zaptel. </span></font> <o:p></o:p></p>
