Questions about new voice service

Questions about new voice service

I recently signed up for voice service with comcast (I previously just had internet and TV) and I have a few questions.

 

If I plug the modem into one existing phone jack in the house will it feed all the other jacks in house so I can have working phones on all of the phone jacks in the house? Also, I read somewhere that this could damage the modem due to feedback - is this true?

 

Do I need to use filters on all of the phone lines? My mother has internet and phone service at her house (through another company NOT Comcast) and she has to use filters on her phone jacks. Is this required with comcast phone service?

 

Is the Comcast Internet and digital voice service bandwidth shared like VoIP? In other words, if I talk on the phone will it slow down my internet in any way, or vise-versa if I am downloading large files on the internet while I am on the phone can it affect call quality?

1.  Not true.  What you are describing is the preferred method to BACKFEED your internal wiring.  If your internal wiring has problems, this may not work on all jacks and you will need the services of a low voltage contractor or electrician to find the fault and make repairs...

 

2.  You need NO DSL FILTERS with Comcast VOIP phone service.

 

3.  Not at all.  Your gateway is comprised of 2 devices.  1 for Data and 1 for EMTA (phone).
