The SonicWALL security appliance supports the most widely used VoIP standard protocols and the
most commonly used VoIP vendors and systems on the market. Providing full VoIP support on the
SonicWALL security appliance enables organizations with increasingly decentralized workforces to
access corporate voice services from remote sites. VoIP systems consist of multiple clients (such as
IP phones or soft phones) and VoIP servers residing at different parts of the network.
VoIP Protocols
VoIP (Voice over IP) is a term used in IP telephony for a set of facilities for managing the delivery of
voice information using IP. In general, this means sending voice information in digital form in discrete
packets rather than in the traditional circuit protocols of the public switched telephone network
(PSTN). A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by
traditional telephone service.
This section provides a concept overview on H.323 and SIP protocols. Refer to the “Configuring the
