What is SIP ALG?
SIP ALG (Application Layer Gateway)
It is common for a router to have this enabled, and it is intended to be a workaround for problems that are caused by firewalls. However, it often affects VoIP service because SIP ALG modifies SIP packets and most commercial routers are not built for VoIP.
