[asterisk-users] Zap Bridged Channels

[Jeremy Mann]

I set it up in general because my voice lines(ports 1-4) had very low volume, and callers complained about outgoing as well, upping both to two seemed to resolve them.

I have a Sangoma A200DX, and am trying to bridge an FXO channel with FXS for modem connectivity.



I have Zap/8 as a Fax Machine



Zap/5 is my outside line.  When a call rings in on Zap/5 it immediately calls Zap/8 and bridges the channels.  I see it doing a native bridge on the two.  I have echo cancel off on native bridge, but I can never get fax connectivity, it just tries to negotiate forever then eventually hangs up.



Anything special to getting this to work?



Below is an example of CLI output when the Fax Machine tries to call out, it does the same thing, never get the two machines to complete the call and send the fax.  I've also included the CLI output of channel 5's properties, it does show the EC as off.  I noticed it says "Fax Handled: no", is there something I need to enable in Zapata.conf or zaptel.conf?



Would txgain/rxgain be the issue?

Gain certainly could be an issue.  Did you set them to 2 for a reason?  If not try 0 gain.

I suspect if you set the communication speed on the fax to a slow speed it will work.  9600 and then bump it up.

Thanks,
