However, in many cases, SIP The FortiGate SIP ALG intercepts, unencrypts , and inspects the SIP packets, which are then re-encrypted and forwarded to their destination. The following configuration examples demonstrate different settings. Learn how to configure SIP ALG and SIP session helper for VoIP traffic passing through the FortiGate firewall. SIP ALG The FortiGate SIP ALG intercepts, unencrypts, and inspects the SIP packets, which are then re-encrypted and forwarded to their destination. SIP ALG (Application Layer Gateway) is a feature commonly found in network devices, including FortiGate firewalls, that attempts to assist with the translation of SIP (Session Initiation Protocol) traffic. The administrator needs to configure two SIP profiles, one with each feature set (voipd and ips), and apply these SIP profiles in the same firewall policy. For Starting with FortiOS 5. Prevent SIP registration problems and dropped calls Additionally, the SIP ALG provides a wide range of features that protect your network from SIP attacks, apply rate limiting to SIP sessions, check the syntax of SIP and SDP content of SIP messages, and provide detailed logging and reporting of SIP activity.
