Question

VOIP and analog phone lines

Dec 2, 2011 11:20AM PST

I just had the Comcast Triple Play set up in my new home. I'm not very familiar with VOIP service. I would like to be able to utilize the analog phone jacks in the house, keeping the modem upstairs in the office and the box from the alarm company (which must be plugged into a phone line) downstairs. Is it possible to somehow send the VOIP signal from the modem through the analog phone lines in the house, so that a telephone (or in this case, the alarm company's box) into a standard phone jack? What would I need to get if this is possible?

They came out and wired the MTA (that's the box Comcast uses) to my house phone wires and it worked.

I'm unsure of your question. Why didn't you let Comcast do the work?

Comcast says...

The guy who installed it said that it could not be done. As a matter of fact, I have a cordless phone system (one base and 3 cordless phones), and I wanted to put the base in the kitchen, but he said that the base must be plugged into modem (understandable), but he said that there was no way to use the analog phone wires in the house. He also said that the MTA (modem) could not be moved to a different location without Comcast's involvement. It had to be configured for the coaxial jack that I chose and would not perform correctly or possibly stop working if I moved it to another coaxial jack in my house. That part I don't believe, but I haven't tried it yet.

It was so simple you had to laugh.

There was a phone jack near the MTA and we plugged a phone cable from the MTA to the phone jack and the house went live.

The MTA stayed there for 5+ years. Never moved it since the system worked.

There maybe lots of misunderstanding here.

Is the telephone line still connected to the phone company box? If yes, then logic tells me the cable company can't mix with the regular phone line with theirs. The interesting question is..can the alarm company uses the phone line from the cable company? As for the base phone, the base itself doesn't have to be next to the modem, but it has to have a line connected between the base and the modem. Here is another possibility; if there is no connection from the "phone co." and your house, then you can connect the house line to the modem. Personally I really don't know how the inner working of all these phone system work. This is just my logic at work here for I may be wrong.
