I’ve got a PBXact server and I’m trying to set up an extension at a remote site. I’m getting the typical NAT issue where it drops after 30 seconds and I can’t hear any audio either way. I have the remote extension pointed to the public IP address of the server and forwarding ports 5060-1 and 10000-60000. I’m able to register no problem.
I’ve added the remote network 10.105.40.0/24 to the local networks in SIP settings and that didn’t seem to help. I could have sworn I was able to do this in the past but I’m not sure what the secret sauce was.
Is the only way this is going to work if I have a VPN established between the two networks?
