Hi,
after replacing (an old) Freebpx installation with 13, the remote extensions are able to register, intitiate calls, but there is no audio.
During the call setup I can see a 401 error, and after a few seconds the line is dropped because no response from the external extension.
We are running a NAT setup, no SIP ALG, same NAT setting as the old freepbx system.
I'm sure it's related to some NAT setting, but I cannot find the right one...
Already tried with the (responsive) firewall disabled, and port 5060 and 10000-20000 forwarded, no luck.What to do..?
