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 traffics.
