9.6.2 SIP ALG
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 ZyXEL Device registers with the SIP register server, the SIP ALG translates
the ZyXEL Device’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 ZyXEL Device is behind a SIP ALG.
Use this screen to enable and disable the SIP (VoIP) ALG in the ZyXEL Device. To access this
screen, click
Network > NAT > ALG
