identified the cause of your problems. Faxing is very time
sensitive. With voice, you won't notice or care if there are brief
dropouts of audio. With fax, these will cause resend of the raster line
(hence the long delays). If your box is shared with other apps, you may
not be getting the time slices you need (very different from overall CPU power
you are getting).</FONT></SPAN></DIV>

<DIV>MD,</DIV>
<DIV> </DIV>
<DIV>Using an analog line is not an option for my service. My application runs
on a ROOT SERVER of an ASP. So I can do anything I want to the server but I
can't connect to or get external analog lines. So my options are doing faxing
via the Internet (VOIP/SIP) or use a faxing service. But my experience with
faxing services has not been too good as I've mentioned.</DIV>
<DIV> </DIV>
<DIV>Does your company provide an affordable, reliable, and somewhat real-time
faxing service? Or can you recommend one? Otherwise, I have to experiment and
try to see the results I can get with doing Internet faxing. Remember my
experience so far with fax service providers - single faxes take 40+ minutes to
eventually be sent (and the delays are within the faxing service and and not the
receiving fax line - I've researched this).</DIV>

Application Faxing using SIP<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV> </DIV>
<DIV>Thanks for the information. I prefer to try to develop/configure
something myself versus using an external provider. I currently use one (have
tried another) and there are no guarantees on reliability, timelines, etc. I'm
in need of as close to real-time response as possible (assuming the fax
machines on the other end are operational). Something like within 5
minutes 85% of the time. My experience with 2 external mailtofax providers so
far is terrible. Just yesterday, a simple 1 page fax took 42 minutes to
finally send it. Other scenarios were 20, 26 minutes, etc. The provider tells
me that they don't gaurantee anything but most of the time sending a single
page fax within 5 minutes 80% of the time. I wish I would see that but so
far I'm seeing terrible response times from the few I've tried. I also need to
know status of fax (in queue, failed, etc) in real-time so my application and
react appropriately (send notification to support staff, etc).</DIV>
<DIV> </DIV>
<DIV>I've found one that does have some sort of guarentee by the cost of
through the roof and would kill my business model/plan (and the gaurantees are
wishy washy). So I think I need to "control" my own destiny.</DIV>
<DIV> </DIV>
<DIV>And this definitely is not anything related to spam fax, etc. - legit
business but right now can't fully reveal.</DIV>
<DIV> </DIV>
<DIV>So I'll have to research abit on IAXModem to use it. But your suggestion
is a good one. Can you share what Asterisk configuration you use to both
receive the iaxmodem feed and interface to the VOIP provider for such a
configuration.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
