(I know this may not work reliably, etc.)
Currently using Asterisk 1.4.x and FPBX 2.3.1…
I’m looking for the best way to set up the following scenario. I have some fax machines that we need to setup to fax out. In our testing so far, we currently setup a prefix to get the call to go out a trunk that forces the codec to be ulaw. We have tested dozens of faxes between 3-15 pages and it’s worked flawlessly. However, I’d like to simplify this, since the users won’t necessarily remember to dal 6 rather than 9 to dial out. Here’swhat I’m thinking as possible solutions:
1 - Use IAXy device, which would allow me to speficy the codec in the definition of the extension, and eliminate the need for dialing 6.
2 - Use external media converter (Quintum/Mediatrix/AudioCodes) to handle the FXS to SIP, and force the codec in the device. Not sure if this can be done, but I don’t see why not.
3 - Setup some sort of custom app/extension that would detect that the extension dialing out is a fax and magically do things…
I’m leaning towards 1 since the cost to some customers would not be a deal breaker. Option 2 would work once the numbe of devices is 4 or more.
My concern is that asterisk will transcode between the ulaw (extension) and g729 (trunk) and ultimately interfere with the delivery of the fax.
Any idead/suggestions?
Thanks in advance,
Carlos.
