Can't receive incoming calls

Can't receive incoming calls

Fax noise on incoming calls.  Unplugged printer but noise is still there

Re: Can't receive incoming calls

Unplug the phone cord from the wall to the eMTA telephony modem.  Plug in a known good wired telephone directly to the L1/L2 jack on the eMTA and give it a test.  You might want to reset the eMTA by pressing the small indented reset button on the panel where the cables attach.

 

If it is now working, then you have other equipment in the home that is seizing the line, which can include water meters, Tivo's and alarm panels.

Re: Can't receive incoming calls

Okay thanks for that...I did try it and still sounds like a fax to others..So we aren't always getting our phone calls. 

 

I don't see how the water line or Tivo would be affecting it..So we are still having this issue again Smiley Sad

It seems as though Comcast is aware of this problem with multiple customers, but passes the buck and has the customer try to fix it themselves. Bad customer service!!

Re: Can't receive incoming calls

Hi JayInAlg,

 

Thanks for any assistance you can provide here.

 

I have Comcast Voice/Internet and a Vector alarm system with an inside panel.

 

The Vector tech has been out twice for signal issues:

 

When we split the line from the wall (before the TM722G modem), the alarm signal is operating correctly, but I cannot get incoming calls as they go to VM.

 

If we split it at the modem jack, the alarm signal will not communicate to the alarm company (but the alarm, mechanically, will work), but the phone will work.  (I also use a fax connection)

 

Either way, outgoing calls are fine.

 

I thought the tech already reversed polarity, or thereabouts,  inside the box.

 

Your thoughts are appreciated.
