Opening Ports

Many routers will work without requiring any additional configuration in the router. If you find that your phone adapter is not able to communicate through your router, then the router is likely incompatible with VoIP, but you can try opening the ports on the router. There are 2 ways to open access through your router:

1) Set your phone adapter to communicate through the DMZ of your router
The De-Militarized Zone of your router will allow all traffic directed at your phone adapter through.

2) Open the specific ports for incoming traffic directed to the phone adapter (port forwarding)
Use port forwarding to open only the necessary ports to the phone adapter

1) Setting your router to use the DMZ for traffic to the phone adapter:

Log into your router.

Set a static DCHP (DHCP reservation) to marry your phone adapter to a specific IP address (save)

Enable DMZ, and set it to the IP address for the phone adapter. (save and reboot)

Reboot phone adapter

2) Port forwarding on your router to allow for VoIP traffic:

Log into your router

Set a static DCHP (DHCP reservation) to marry your phone adapter to a specific IP address (save)

Set up port forwarding on your router. You must specify that ports 5060-5061 (UDP), 53-53 (UDP),
69-69 (UDP), and 10000-20000 (UDP) are forwarded to the IP address of the Phone Adapter.
