Why DrayTek’s Secure Phone
Key exchange method is not standardized => incompatible between different brands.
•ZRTP: draft to specify it, and it's up to draft 14 already, will become RFC soon.
•Implies: zrtp + srtp will be the standard protocols for secure phone.
• DrayTek should be the first company in the world that supports ZRTP+SRTP secure phone feature (i.e. zfone compatible).
