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?

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?
