Abstract
A method for supporting non-secure warning tones on packet-switched networks involves receiving a call attempt from a source phone to a destination phone, checking if a connection of the security domains of the source phone and the destination phone via a MLS voice gateway is allowed, and checking if a generation of a non-secure warning tone locally by the source phone is required. A call is established from the source phone to the destination phone upon acknowledgement of the local generation of the non-secure warning tone by the source phone.
