Troubleshooting
Possible Solution
• If you use a cordless phone, check that the base of your phone is
turned on and receiving power and that the cordless phone battery
is not low.
• Check that the phone cable connections are secure at the cable
modem and at base of your phone, and that the cable modem is turned
on and receiving power.
• Check that call forwarding is not enabled.
• If you use a cordless phone, check that the ringer is not turned off.
It is possible that the calling party blocked its caller ID. If this is true, you
might be able to program your phone to recognize an incoming number
and associate a name with that number.
