Connecting an IP Phone to Voice Modem

Connecting an IP Phone to Voice Modem

I recently purchased a polycom 335 IP Phone to connect to the Comcast Voice service.  I cannot register this phone.  Is there certain addressess or settings I need in order to make this phone work?

Re: Connecting an IP Phone to Voice Modem

Comcast may be VoIP, but the pohnes themselves still need to support POTS, as the incoming line into the individual is still a traditional phone line. If you are using 3rd party VoIP services like vonage, etc, then it would use the internet, not the phone service.
