Title: VoIP Secure Communication
Protocol Satisfying
Backward Compatibility
Abstract: Several VoIP security protocols
have
been standardized for preventing many VoIP threats. But since several
VoIP
carriers have different VoIP protocols, end-to-end VoIP secure
communication
can not be possible. Also when initiator using secure VoIP phone wants
a
secure communication with responder using non-VoIP phone such as PSTN
phone,
or cellular phone, etc, so does it. Therefore, we propose VoIP secure
communication
protocols satisfying backward compatibility.
