Disable SIP ALG

Hi folks,

We have a pair of SG450 Hardware Appliances (Hot-Standby Mode) running UTM Version 9.705-3 acting as Web Proxy Firewalls at the edge of our internal network.

We are winding up a few loose ends from a recent VoIP implementation and I have been asked by our VoIP vendor to confirm that SIP ALG is disabled on our Sophos UTM installation. SIP Protocol Support is disabled globally. Does this mean SIP ALG is disabled? I see that there is a command (system system_modules sip unload) which takes care of this on XG appliances, but I cannot see a similar command for the UTM appliances.

Any assistance would be much appreciated.

Best regards,

John P
