Deployment Scenario 2: Public VoIP Service
The Public VoIP Service deployment uses a VoIP service provider, which maintains the VoIP
server (either a SIP Proxy Server or H.323 Gatekeeper). The SonicWALL security appliance
public IP address provides the connection from the SIP Proxy Server or H.323 Gatekeeper
operated by the VoIP service provider. The following figure shows a public VoIP service
topology
For VoIP clients that register with a server from the WAN, the SonicWALL security appliance
automatically manages NAT policies and access rules. The SonicWALL security appliance
performs stateful monitoring of registration and permits incoming calls for clients while they
remain registered. No configuration of clients is required. See the “
Using the Public Server
Wizard” section for information on configuring this deployment.
