Service Zone Settings – SIP Interface Configuration

The system provides SIP proxy functionality, which allows SIP clients to pass through NAT. When enabled, all

SIP traffic can pass through NAT via a fixed WAN interface. The policy route setting of SIP Authentication must

be configured carefully because it must cooperate with the fixed WAN interface for SIP authentication.

SIP Transparent Proxy can be activated in both NAT and Router mode. SIP Authentication must support in

either mode. For users logging in through SIP authentication, a policy can be chosen to govern SIP traffic. The

policy’s login schedule profile will be ignored for SIP authentication. Specific route and firewall rules of the

chosen policy will be applied to SIP traffic.
