SCOPIA XT Series as Endpoints
Planning NAT and Firewall Traversal with SCOPIA XT Series
SCOPIA XT Series fully supports NAT and firewall traversal, enabling you to place the unit
behind a NAT router or firewall and connect with other endpoints seamlessly. This section
describes four approaches to NAT and firewall traversal with XT Series:
•
Using a RADVISION HTTP server or a STUN public server for NAT and firewall traversal
When the XT Series hosts a videoconference with endpoints outside the enterprise (
Figure
1-2 on page 5
), it first queries the HTTP or STUN server to discover its public IP
address, then sends it to any external endpoints wishing to join the conference. The
external endpoints then answer the call using the IP address provided. Configure the XT
Codec Unit for HTTP or STUN autodiscovery.
