STUN
12.11.4 Outbound Proxy
Your VoIP service provider may host a SIP outbound proxy server to handle all of the
Prestige’s VoIP traffic. This allows the Prestige to work with any type of NAT router and
eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of
the Prestige to keep it from retranslating the IP address (since this is already handled by the
outbound proxy server).
12.12 NAT Traversal Configuration
Click
NAT TRVSL
to open the following screen where you can configure your Prestige to
operate through a NAT router that is not SIP-friendly.
The following screen displays the IP address and port number of an outbound proxy server the
Prestige uses to connect to the outbound proxy server.
