SIP/H.323 ALG configuration example

H.323 ALG configuration is similar to SIP ALG configuration. The following example describes SIP ALG
configuration.
The example describes only ALG configurations, assuming other required configurations on the server
and client have been done.
Network requirements
As shown in
public network addresses: 5.5.5.1, 5.5.5.9, 5.5.5.10, and 5.5.5.1 1. SIP UA 1 is on the internal network
and SIP UA 2 is on the external network.
Configure NAT and ALG on the router to enable SIP UA 1 and SIP UA 2 to communicate by using their
aliases, and to enable SIP UA 1 to select an IP address from the range 5.5.5.9 to 5.5.5.1 1 when
registering with the SIP server on the external network.
