9. Check the Enable option for the port services you want to use.
10. When you have completed the configuration, click the Save Settings
button.
2. When I’m on a telephone call, words are dropped intermittently.
Go through this checklist until your problem is solved:
• Are you using a wireless router and cordless phone? If so, the router and
cordless phone may be using the same frequency and interfere with each other.
Move the cordless phone farther away from the router.
• There may be heavy network activity, particularly if you are running a server or
using a file sharing program. Try to limit network or Internet activity during any
Internet telephone call. For example, if you are running a file sharing program,
files may be uploading in the background even though you are not downloading
any files, so make sure you exit the program before you make an Internet phone
call.
• There may not be enough bandwidth available for your Internet phone call. You
may want to test your bandwidth using one of the bandwidth tests available
online. If necessary, access your service account at your Internet phone service
provider’s website, and reduce the bandwidth requirements for your service. For
more information, refer to your Internet phone service provider’s website.
• There may be too many wireless routers or access points in your location using
the same broadcast channel. Try changing the channel that your wireless router
or access point uses; refer to the documentation of your router or access point for
instructions.
3. The IP Phone does not ring, and my calls automatically go to voicemail.
Go through this checklist until your problem is solved:
• Check the ringer volume on the IP Phone, and make sure it is set to an audible
level.
• Follow these instructions to reboot your cable or DSL modem, IP Phone, 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 IP Phone by pressing and holding down the Power
button for two seconds.
4. Wait 30 seconds, and then power on your cable or DSL modem by
plugging its power adapter into an electrical outlet.
5. Wait 30 seconds. Power on the router by plugging its power adapter
into an electrical outlet.
6. Wait 10 seconds. Power on the IP Phone by pressing and holding
down the Power button for two seconds.
7. Reboot one of your networked computers, and check for an active
Internet connection.
• Set up port forwarding on your router. You must specify that four port ranges be
forwarded to the IP address of the IP Phone. These four port ranges are as
follows: 5060-5061 (UDP), 53-53 (UDP), 69-69 (UDP), and 10000-20000 (UDP).
Note: By default, the IP Phone uses a dynamic IP address assigned by your router. For port
forwarding, you may need to assign a static IP address to the IP Phone. Contact your Internet
phone service provider for assistance.
If you have a non- router, refer to its documentation for instructions.
If you have a router, then follow these instructions:
1. On one of your networked computers, open your web browser.
