8.5 Port Security
If the VoIP network contains a firewall, the firewall must be configured appropriately to allow VoIP packets to
pass through certain ports of the ports listed below without being blocked by filtering. The ports for which you
need to configure the firewall may vary depending on the network conditions.
For more information, consult your network administrator.
The following table shows the PBX’s ports used for IP communications. Any access to the ports not in this list
is ignored.
