Security Configuration Snom phones do not verify server identities by default. From firmware version 8.2.30 you can explicitly state to verify server certificates though. You can activate the feature on the certificates page of the web interface: The phone will reject all secure connections of peers offering an unknown certificate that could not be verified by one of buildin CA's of the Snom phone. Please refer to the Certificate Authorities tab to see which authorities are supported by the phone. Due to security concerns, you can only disable the feauture by resetting the phone to the factory defaults.
