IP address that is either dynamically assigned at startup or permanently assigned.
All TCP/IP messages contain the address of the destination network as well as
the address of the destination station. This enables TCP/IP messages to be
transmitted to multiple networks (subnets) within an organization or worldwide.
VAD
Voice Activity Detection (VAD) helps save bandwidth during calls. Examples:
When you making a VoIP call and your not speaking and your listening, that
silence is still taking up bandwidth during the call. When silence is detected by
VAD software over a predetermined length of time, it sends silent packets that
inform other VAD enabled systems to stop holding the bandwidth for these empty
packets.
VoIP
Voice Over Internet Protocol: VoIP is based on the principal of transmitting
digitized voice packets over networks. Basically, VoIP consists of converting voice
signals into streams of digital packets and sending those packets of data through
an IP-constructed network environment. VoIP can work in both LAN (local area
network) and WAN (wide area network) environments for intranetwork or
internetwork communication between VoIP channel users. Routers and switches
and other special compression protocols direct the packetized voice data to their
destination IP address. VoIP can be less expensive than voice transmission using
standard analog packets over POTS (Plain Old Telephone Service). It allows
telephone calls, faxes, or overhead paging to be transported over an existing IP
data network topology.
