Vendor ID filtering

With H.323 filtering, you can enable filtering for vendor IDs and direct-dialing. The Enable H.323 Vendor ID Filtering option limits incoming calls to vendors with signaling parameters that match industry hardware whitelists. The Enable Checking Dialed Digits option verifies the call setup message information matches the information for the user placing the call. If not, the call is blocked.
