VoIP
(supported models)
Voice-over-IP (VoIP) refers to the ability to make voice telephone calls over the Internet. This differs from
traditional phone calls that use the Public Switched Telephone Network (PSTN). VoIP calls use an Inter-
net protocol, Session Initiation Protocol (SIP), to transmit sound over a network or the Internet in the
form of data packets. Cer tain Motorola Netopia
