In certain situations, it may be desired to use a VoIP (Voice over IP) device with the SBG6580.  The SBG6580 is compatible with VoIP SIP (Session Initiated Protocol) devices, as it includes the SIP ALG Passthrough feature, which is enabled by default.
For VoIP devices that do not use SIP, the SIP ALG Passthrough feature may need to be disabled in the SBG6580.  In some cases, the SBG6580 may also need to be configured to forward ports to the VoIP device.
For more information about SIP ALG Passthrough, please refer to the following FAQ:
