the incoming (by email) fax document, and the time to fax the document.
Fax over IP causes an enormous number of retries - thus delays. I would
suggest you do some experimenting with an analog line connected to your asterisk
box.</SPAN></FONT></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>

time.<BR>><BR>> Thanks in advance for the help,<BR><BR><BR>The missing
