Simon I think PVX's key exchange mechanism is in a standard way. PVX and Codian MCU can connect using AES. But I don't know how the shared secret is used to produce the session key. Bian

No PacPhone AES uses a different key exchange mechanism to PVX. Polycom uses a proprietry method. They should still connect unencrypted.

The shared secret is used to encrypt the key exchange material to generate the cipher for media encryption. If the shared secret was public knowledge then anyone can intercept the key exchange and generate a key to decrypt the media. So unless Polycom or Codian wish to share that proprietry secret there is no way to connect via AES. Simon
