Port Ranges
•
First UDP-RTP port, Number of ports: These values
define, in which area the negotiation of the RTP port
shall take place. This is useful if the network is
secured by a firewall and only certain ports are to be
opened for telephony. As soon as the routers
support prioritisation via port number, the port
settings can also be used to influence the priority in
the network.
•
First UDP-NAT port, Number of ports: If the VoIP
telephone works as a DSL Router, and the internal
network works with unroutable IP addresses,
Network Address Translation (NAT) is used. With this
setting, the NAT service can be limited to certain IP
ports.
Local Networks
Here you can declare IP addresses or address ranges to be
part of the
local network

This configuration influences the coder selection process on
VOIP endpoints like telephones and physical Gateway
interfaces. (See chapter 4.7.1.1 on page 226)
Private Networks
Here you can declare IP addresses or address ranges to be
part of the
private network
.
4.5.1.2

•
Gateway: IP Address of the next gateways
