6.3.4 ALG

SIP ALG is Application layer gateway. If the user has an IP phone(SIP) or VoIP
gateway(SIP) behind the ADSL router, the SIP ALG can help VoIP packet
passthrough the router (NAT enabled).

Note

: SIP (Session Initiation Protocol, RFC3261) is the protocol of choice for most

VoIP (Voice over IP) phones to initiate communication.
