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 tables show the PBX ports used for IP communications.
Any access to the ports not on these lists are ignored.
