Re: modem

You need to buy a Telephone modem and that SBD6580 is just a modem router. 

 

Go here to find the correct device.

Tthe Arris TM722G or TM822G is what you need.

Re: modem

You need a telphony modem for Xfinity voice.  You will either need to get it from Comcast or if your area allows you to own a voice modem get one like the Arris TM822g to replace the modem you purchased for internet alone.

 

You might be able to use the one you bought for internet and add a second voice/internet modem provided by comcast with the internet portion shut off.

From what I am seeing on the web if you have voice service you will need to get permission from your local comcast  to replace the Arris TM722G EMTA Internet Voice Modem. It also seem that they my charge you a fee to install it based on your market. I can also tell you that it seems pretty common for the battery to go bad in that model. If you currently own that EMTA then you may consider simply replaceing the battery and calling up tech support to have them send it a new signal.

 

You will want one of the telephony modems or gateways listed on http://mydeviceinfo.comcast.net/ in any case. If it does not say telephony or EMTA then it will not support your voice. The only places I have seen them for sale is best buy and amazon. I would definately stay away from their gateways though if possible as Comcast enables WiFi hotspot on the gateways and you may have problems getting it disabled.

 

I hope this helps

Have you tried using the recessed reset button on the rear ? Depress and hold it in until you see the front panel lights begin to cycle. Now give it the time that it needs to fully re-synch with the system. Any better ?
