To disable SIP (Session Initiation Protocol) application level-gateway in a firewall, you will typically need access to the firewall configuration. The steps to disable SIP ALG (Application Level Gateway) can vary depending on the firewall device and its software version.

1. Access the firewall configuration: Log in to the firewall's management interface using a web browser or SSH (Secure Shell) client, depending on the firewall model and configuration.

2. Locate the SIP ALG settings: Look for a section or menu specifically related to application-level gateways or SIP settings. This may be labeled as "SIP ALG," "SIP Inspection," or similar.

3. Disable or turn off SIP ALG: Once you've found the appropriate settings, there should be an option to enable or disable SIP ALG. Choose the option to disable it.

4. Apply the changes: Save the changes made to the SIP ALG settings and apply them to the firewall configuration.

5. Reboot or restart the firewall : Some firewalls may require a reboot or restart for the changes to take effect. Check the documentation or contact the firewall vendor if necessary.

6. Test the configuration: After disabling SIP ALG, it is important to test your SIP applications and ensure they are functioning correctly without any interference from the firewall.
