No Audio Fxo To Fxs

Grrr.. It was working now it is not. FXO to SIP works perfectly, and FXS to SIP is perfect also.

Interestingly, and outbound FXS call has one way audio (outbound).

I wish I could tell you what has caused it to stop working. We added Ring Group and Follow Me modules, and some additional outbound routes - can't image that would break FXO-FXS.

Here is my ZAPATA.CONF.

Thanks for any help you can offer

Well - its now working.

I read on a forum that echotraining=800 in zapata_additional.conf which need to be changed to echotraining=0 on the FXS channel extension.

Although the extension now worked - it broke CallerID!

So - I removed the following lines from ZAPATA.CONF
cidsignalling = v23
cidstart = polarity

My ZAPATA.CONF now looks like this:

So - it now works with CallerID. I'm not going to touch anything now for a while!

Hope this is helpful to someone.
