Strange incoming phone ringing

Strange incoming phone ringing

When my phone rings at my house, the rings is sometimes very looooooooong & sometimes very, very abrupt & short. My caller I.D. can't register these calls. What is going on???

Re: Strange incoming phone ringing

Try resetting the eMTA telephony modem first, press the small indented button on the back panel.  You will need a toothpick or some poker to press it.

 

Next, try a known good wired telephone and connect it directly to the eMTA's L1/L2 jack and try it for a while.  That will eliminate any wire or phone equipment issues.

 

If it continues, then please contact Comcast support and they will need to send out a tech who most likely replace the eMTA telephony modem.

Re: Strange incoming phone ringing

Can I keep my cordless phones plugged in to my wall jacks or should those be disconnected?

Re: Strange incoming phone ringing

In order to connect a phone to the L1/L2 jack, you will need to unplug the cord going to your inside wiring.  That will disconnect all your phones in the home.  So no, you do not need to unplug them from their jacks.
