HI,
I have noticed that when i call in from VPN the call works okay. If another call is in progress then there is no audio on second call. All calls ring and then no answer so i assume it is the NAT issue on freepbx.
do I need to open firewall ports on VPN?
any pointers on NAT and freepbx and draytek 2860 vigor.
