Phone problems!

Phone problems!

We recently upgraded to the Triple Play package, including 2 phone lines and an Arris TM722 modem.  One phone line is in our main house and the other is in the mother-in-law (MIL) house, which is a smaller house located only 50' from the main house and is actually occupied by the MIL.  We've had numerous problems reported in the smaller house by the MIL:


- The phone rings, she checks the caller-id, then picks up the phone to find that the line is dead.  This happens a LOT, but not every time.


- During a conversation the MIL gets a call waiting signal and attempts to change over to the other call, but this doesn't work - another intermittent problem.


- She calls the main house, when we pick up the line goes dead.  This is another intermittent problem.


- Caller-id doesn't always register the name/number of the caller.



In the main house, our only problems relate to the MIL house:


- We answer the phone line to a dead line, the caller-id says the call is from the MIL house.


- We call the MIL house, we hear the phone being picked up but then it immediately goes dead.



FWIW, our Triple Play Comcast service is loaded with the following:


- High speed Internet, including a router with all 4 Ethernet lines in use and even wireless used at times


- 3 DVR's, 1 STB, and 1 DTA.


- 2 phone lines.



Could it be that the Comcast service is having hiccups from too many items in use on a single cable?



Any help would be appreciated!


Thanks, Bill

Re: Phone problems!

The fact that you only get a problem with the MIL's phone suggests a problem with the wiring to her place or the phone. To troubleshoot you could disconnect the MIL's line, then connect a known good phone direct to the back of the modem for a while.. See if things improve.


If it does improve you would need someone to check out the wiring. Having all those devices should be fine as long as you get a good signal.


Just to add, not sure if the distance to the MIL's place would be a factor here.

There were problems with our old phone lines, so I had a new line run from the back of the modem to the MIL house and a new outlet installed.  I've since run continuity checks on the new line but it's fine.  BUT - I do intend to move the phone from the MIL house back to the main house once the MIL goes back north (we're in southern AZ) for the summer.  But since the cable checks out to be fine, I don't expect moving the phone will show any differences.  Thanks for the input though!
