Voice Modem Needed - Please Advise- Very Confused!

Voice Modem Needed - Please Advise- Very Confused!

We have Triple Play, Performance Pro, Blast Internet.  Recently we replaced our internet router with a purchased Arris SBG6580 which sits in our kitchen.    Everything seemed fine. The separate voice modem was an old RCA Model DHG535-2 which was with the hoome when we bought it.  It has been in the garage working for 5 years.


Now 2 weeks later, I have no dial tone on the home phone lines, and there is no power going to the old RCA voice modem.  I assume it has died and I need to replace it.  We have one home phone line with 5 hand helds throughout the house. 


Can the Arris SBG6580 work as an internet and voice modem?  If not, what specific Comcast approved eMTA voice modem should I buy? Or do  I need somethign else?  Thanks!!

The ones that say TELEPHONY in the description.


Only one on the list approved with the RETAIL Purchase check mark it seems.  Another Gateway modem/router device.  You can call the local franchise and ask if there are other Customer Purchase approved telephony modems.




 Or you might private message ComcastFrancisc and ask him, he is a comcast employee.
