Internet Phone Adapter with 2 Ports for Voice-over-IP
2. When I make a telephone call, the call doesn't go through; instead, I hear a fast busy signal.
Go through this checklist until your problem is solved:
• Pick up your phone and dial 1 + area code + phone number. Some Internet phone services require that
you dial 1 and the area code for all calls, even local ones.
• Follow these instructions to reboot your cable or DSL modem, Phone Adapter, and router:
1. Power off your cable or DSL modem by unplugging its power adapter.
2. Power off the router by unplugging its power adapter.
3. Power off the Phone Adapter by unplugging its power adapter.
4. Wait two minutes, then power on your cable or DSL modem by plugging its power adapter into an
electrical outlet.
5. Wait two minutes, then power on the router by plugging its power adapter into an electrical outlet.
6. Wait five minutes, then power on the Phone Adapter by plugging its power adapter into an electrical
outlet.
7. Reboot one of your networked computers, and check to see if you have an active Internet
connection.
8. Pick up the telephone. You should now have a dial tone.
• 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.
Before you set up port forwarding on your router, change two of the Phone Adapter's settings using its
Interactive Voice Response Menu. First, disable its DHCP feature, then assign a static IP address to the
Phone Adapter. See "Chapter 4: Using the Phone Adapter's Interactive Voice Response Menu" for
instructions.
If you have a non-Linksys router, refer to your router's documentation for instructions.
