The following table describes the fields in this screen. 

11.6  The ALG Screen

Some NAT routers may include a SIP Application Layer Gateway (ALG). A SIP ALG allows SIP calls to pass 
through NAT by examining and translating IP addresses embedded in the data stream. When the EMG 
registers with the SIP register server, the SIP ALG translates the EMG’s private IP address inside the SIP 
data stream to a public IP address. You do not need to use STUN or an outbound proxy if your EMG is 
behind a SIP ALG.

Use this screen to enable and disable the ALGs in the EMG. To access this screen, click
