To disable SIP application level-gateway (ALG) in Sangfor firewall, follow these steps:

    Log in to the web interface of your Sangfor firewall.
    Go to Security > Application Control > ALG.
    In the SIP ALG section, uncheck the Enable SIP ALG checkbox.
    Click Save to apply the changes.

Note: If you are using Sangfor NGAF, you can also disable SIP ALG from the Firewall > ALG page.

Disabling SIP ALG may be necessary if you are experiencing problems with your VoIP service, such as one-way audio or call failures. However, it is important to note that disabling SIP ALG may also reduce the security of your VoIP network. Therefore, it is important to only disable SIP ALG if you are sure that it is necessary.
