My provider switched me to an IP-based line. Now my analog ISDN (G3) Fax does not work anymore.

Is there any way I can use the conventional Fax with a SIP connection? My Router supports T.38 Fax protocol as well as many codecs.

I've setup an IVR to pickup up incoming calls to allow them to enter an extension or press one to be dropped into the ring group for our office. The only issue is Asterisk isn't playing the WAV/MP3/GSM audio file I upload. Using a default recording works , I'm not sure why mine won't. I also know the IVR works because I can enter an extension after it stops ringing. I am using Elastix as a GUI to Asterisk.

Here's a snippet of the "full" log file as contained in /var/log/asterisk:

I'm not a phone guy at all, but I have a strange problem. One of my clients' staff members has several fax machines on the same line (with staggered answering on number of rings for failover). I believe they dial out on whatever rollover line is available, but I'm not positive. I can certainly clarify this if required.

Anyways, their Windows Fax Service users and their Multi-function Printer fax users are experiencing an intermittent issue where they're manually keying in a number on the fax machine (as well as typing it into Outlook for the Windows fax users) and it's going to a different number, as in the "wrong" number people are calling back and saying, "why did you fax this to us?". Now it's not just any number, it's going to another regularly faxed destination, just not the right one.

So I'm wondering if two machines are trying to fax at the same time and getting "the lines crossed".

Is this possible that there's some sort of cross-talk or "routing" issue? Again, absolute dullard when it comes to POTS.

EDIT

Found out that Sally wants to fax to 555-1234, but it's going to 555-5678. At roughly the same time, Bob has been getting a "failed" fax response when trying to fax to 555-5678, so there's definitely some "cross-over/cross-talk" happening.

I'm not sure this is the right forum for this, but it's not Stackoverflow so...

I'm trying to figure out an architecture to solve the following problem, maybe someone here can help:

I have a T1 with 23 fax lines coming into the building. I have a computer (Macintosh XServe) running Hylafax. If I had one POTS line, I'd be done. However, I have no idea how to get the T1 into the Mac...

Options I've considered:

  • some sort of PCI T1-modem (Does that exist?)
  • Splitting the T1 into 23 POTS lines and then connecting 23 analog modems to the mac, either via an external modem bank (Do they still make those?) or via some sort of external PCI bank, which will allow me to use more than 2 4-port modem cards.
  • Either the T1 or the split POTS lines going into some intermediate device and then transfering the images over IP, or USB to the mac.
  • Really, any other option I can come up with

This has GOT to be a problem that someone has already solved, right?
