Configuring the Endpoint for Use with a Firewall or
NAT
A firewall protects an organization’s IP network by controlling data traffic from outside the
network. Unless the firewall is designed to work with video conferencing equipment, you must
configure the firewall to allow incoming and outgoing traffic to the VC110 endpoint through the
reserved ports. Users placing calls through a firewall to endpoints may experience one-way
audio or video if the firewall is not properly configured.
Call Setup and Media Ports
To place calls to other endpoints through the firewall, you must configure your firewall to allow
incoming and outgoing traffic to the system through the following:
SIP (default transport protocol)
SIP (when selecting the TCP transport
protocol)
SIP (when selecting the TLS transport
protocol)
Reserved ports of the endpoint.
