Configuring your System for Firewall Traversal
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 VC800 system through the
reserved ports. Users placing calls through a firewall to systems may experience one-way audio
