VoIP phone configured to FW interface

fmnh_support

I'm trying to test out VoIP system by connecting a VoIP phone directly to an available firewall Ethernet interface. I'm having some configuration problems getting the phone out to the internet to establish a connection to our VoIP provider. This is to test the latency/voice quality problems we are experiencing on our internal network. Please advise.

    What VoIP Protocol?

    Ask your phone provider for a list of needed IP addresses and port ranges. Then, open them up.

    Ensure you have an exclusion set within IPS if you have that enabled. 

    Ensure the traffic is being NAT'd correctly so it can actually get externally. 

    If using SIP or H.323 try the built in VoIP helpers.
