<div class=Section1>
<p class=MsoNormal>I am testing out hylafax and iaxmodem. Submitting jobs
to the hylafax server and having it then dial using iaxmodem is working
fine. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hylafax server is talking to my Asterisk box that has
a Sangoma A101 in it via iaxmodem via an IAX channel using ulaw.<o:p></o:p></p>
<p class=MsoNormal>A call coming into a certain test DID comes into the Sangoma
A101 then it goes to another box via IAX ulaw that uses the rxfax app to
capture the fax. I am using rxfax right now because I am just starting to
test hylafax.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Normal faxes into my test DID work fine so I know it’s
not the Sangoma or rxfax app or communication between those 2 servers. I
notice the Sangoma detects incoming fax tones for these faxes.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, if I send the fax via iaxmodem, I notice the
Sangoma sends the call out via my trunk group that turns off the echo
cancellation (Because I am using a group I setup to do that, there it’s
surprise there) but when it comes back in, the Sangoma is not turning off echo
cancellation. The end result is rxfax gets the tiff image, but then the
call just hangs up and the pdf is never created and sent. The Tiff image
appears to be complete however but the call just hangs up after that.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I think the problem is due to the Sangoma not detecting the
fax tones. Am I missing a setting with iaxmodem or hylafax?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>To recap:<o:p></o:p></p>
<p class=MsoNormal>Test DID works fine with normal analog and other fax via ATA
adapters so I think I can safely rule out a misconfiguration there<o:p></o:p></p>
<p class=MsoNormal>Iaxmodem registered, hylafax clearly sends the fax via it as
I see it coming back in and the tiff created using rxfax<o:p></o:p></p>
<p class=MsoNormal>The problem appears to be coming back – echo cancellation
not being turned off.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Unfortunately like many of us, I don’t have a test PRI
server I can play with so I have to do this after hours. I will be
turning off echo cancellation late at night and seeing if that solves the
problem but wanted to pose this question to the list.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have _<i>not</i>_ tested it to an outside analog fax yet
via hylafax/iaxmodem.<o:p></o:p></p>
