SIP ALG modifies the destination addresses of VoIP packets causing reliability issues. Implementing the necessary changes to disable SIP ALG can oftentimes resolve these issues. In many cases, a properly configured system may still have audio issues when transmitting or receiving calls where only one party is heard during a call. One of the most common issues with VoIP solutions relates to audio transmission and presence of a firewall and/or NAT traversal being configured. The SIP protocol is one of several protocols managed by this system. Certain protocols are processed by the application layer gateway (ALG) and rewritten to allow better flow through a firewall or when NAT (Network Address Translation) is employed. SIP ALG : SIP ALG (Application Layer Gateway) is a mechanism found in most routers that rewrites packets transmitted across the device.

If an incoming call is made to a Hide NATed address, Security Gateway verifies that the user exists in the SIP registration database. When this service is used, registration message are tracked and a database is maintained that includes the details of the IP phones and the users. Use a VoIP Domain in the source or destination of the rule, together with this service. This service is used to enforce signal routing. If you use service SIP UDP with protocol type SIP_UDP an inspection is always done.
