Ok. Now CloudPBX is able to try dialong the extension on PBX1. No more cause 50.
Im getting a new hang up cause. It is caise 16. Any ideas what is it about?

again you will need to debug the IAX2 connection. and without complete logs, no-one will guess.
Thanks. I got it solved out. First, it was some configuration on the incoming part of each PBX. I did configure it as I had incoming settings all blank.
Second it was a network issue, I did forward port 4569 on each router to its PBX.
Last I had a problem on the receiving extension thats why I was getting hang up cause 16. I used another extension and cause 16 never appeared.
That’s exactly how it is documented, well done!
