I’m having trouble with Sangoma talk app. It keeps trying to register
but fails with “effective transport unspecified”. Has anyone solved
this? I have a Fortinet firewall with port 5061UDP and RTP10000-20000
open, but RTP ports are closed when scanne...
After some digging, I was able to address the issue by switching the
transport from tls to udp and it now works. I applied some hardening to
the policy. Thank you for your help.
