IP Telephony
Introduction to IP Telephony
IP telephony, namely voice over Internet Protocol (VoIP), is also called broadband telephony or
Internet telephony. It utilizes Internet Protocol (IP) network technologies to implement voice
communication. During a VoIP call, voice signals are digitized, encoded, packetized, and transmitted
as packets over a network. On the receiving side, the packets are then decoded, and digital signals
are converted to reproduce the original voice streams, which can be heard by the called party.
Different from traditional PSTN calls, VoIP calls are transported over IP networks, meaning voice
streams are transmitted over users' existing broadband Internet. This makes full use of broadband
resources.
Configuring VoIP
The HG658 V2 supports VoIP. You can place VoIP calls after your phone is connected to the
Phone
port on the HG658 V2.
To use the HG658 V2 to place VoIP calls, ask your network service provider to activate VoIP services
for you. By default, your network service provider will have all related parameters, such as the VoIP
account and address, set for you. You will not need to configure any settings to place VoIP calls.
To configure voice services, do as follows:
1.
