<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> <div>J<BR><BR><B><I>Philip Edelbrock <phil@netroedge.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"><BR><BR>On Feb 18, 2006, at 11:35 AM, J Poz wrote:<BR><BR>> I have a specific business problem that I'm
