78.1 VoIP Overview
Use the VoIP commands to configure VoIP on an ONT (Such as the PMG5318) through OMCI.
VoIP is the sending of voice signals over Internet Protocol. This allows you to make phone calls and send
faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone
network. You can also use servers to run telephone service applications like PBX services and voice mail.
Internet Telephony Service Provider (ITSP) companies provide VoIP service.
Circuit-switched telephone networks require 64 kilobits per second (Kbps) in each direction to handle a
telephone call. VoIP can use advanced voice coding techniques with compression to reduce the
required bandwidth.
78.1.1 SIP
The Session Initiation Protocol (SIP) is an application-layer control (Signaling) protocol that handles the
setting up, altering and tearing down of voice and multimedia sessions over the Internet.
SIP signaling is separate from the media for which it handles sessions. The media that is exchanged
during the session can use a different path from that of the signaling. SIP handles telephone calls and
can interface with traditional circuit-switched telephone networks.
78.1.1.1 SIP Identities
A SIP account uses an identity (Sometimes referred to as a SIP address). A complete SIP identity is called
a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a way similar to
the way an e-mail address identifies an e-mail account. The format of a SIP identity is SIP-Number@SIP-
Service-Domain.
78.1.1.2 SIP Number
The SIP number is the part of the SIP URI that comes before the “@” symbol. A SIP number can use letters
like in an e-mail address ([email protected] for example) or numbers like a telephone number
([email protected] for example).
78.1.1.3 SIP Service Domain
The SIP service domain of the VoIP service provider is the domain name in a SIP URI. For example, if the
SIP address is
, then “VoIP-provider.com” is the SIP service domain.
