The phone(s) attached to the SpeedTouch™ can receive incoming VoIP
calls, as long as your SpeedTouch™ is turned on and the VoIP Ready LED is
lit.
For calls over the regular phone line, your phones are line powered by the
telephone company and can therefore always be reached, even if the
modem is turned off.
