So I have a PBX up and running and I’m registering phones remotely over the internet. I have ports 5060, 5160, and 10000-20000 open on the firewall. When I try to call an extension or say *43 I get no audio. From the logs it looks like the call goes through fine. Here is a sample output from the Asterisk log file. “WAN_ADDRESS” is the IP that my phone is located on and “192.168.1.48” is the phones LAN address.
