Overview
Network communication is defined by network protocols. A network
protocol is a formal set of rules, conventions, and data structure that
governs how computers exchange information over a network. In other words,
network protocol is a standard procedure and format that two data communication
devices must understand, accept, and use to be able to talk to each other. |
|
SIP Protocol
Session Initiation Protocol (SIP) is an application layer control protocol
for creating, modifying, and terminating sessions with one or more participants.
Functions/features on SIP enabled phones can only be changed through the
user portal. |
|
MGCP Protocol
Media Gateway Control Protocol (MGCP) is used for controlling telephony
gateways from external call control elements called media gateway controllers
or call agents. Functions/features on MGCP enabled phones can be
changed through the user portal or the handset. |

| In order to enable organizations to adopt VOIP as a viable solution,
its components must be able to perform the same functions as the PSTN network.
The basic functions of VOIP as they compare to the PSTN are: |
|
-
Signaling - is the way devices communicate with the network, activating
and coordinating the various components needed to complete a call.
In a VOIP network, signaling is accomplished by the exchange of IP datagram
messages between the VOIP components.
-
Database services – are a way to locate an endpoint and translating the
addressing that two networks use. The generation of reports for billing
purposes is another feature. The PSTN uses telephone numbers to identify
endpoints. A VOIP network uses an IP address and port number to identify
an endpoint.
-
Call connect and disconnect (bearer controls) - the connection of a call
is made by two endpoints opening a communication session between one another.
When a communication is complete, the IP sessions are released and network
resources freed.
-
CODEC operations - traditional voice communication is analog, while data
networking is digital, as a result, the network needs a way to be able
to convert the voice into a format that it can transport. For VOIP, it
is necessary to “packetize” the voice. This process is done with a coder-decoder
(CODEC).
