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 VoIP Settings” section for configuration tasks for H.323 and SIP networks.
