I am trying to setup secure calls with H.323 endpoints. I am currently testing with polcom PVX.<br><br>I can negotiate a shared secret using diffie-hellman and the first 8 bytes of the shared secret match the PVX&#39;s check code.<br>
<br>But how to derive the media encryption keys from the shared secret ?<br><br>From H.235.6 I understand that the shared secret must be used to decrypt encryptedSessionKey, but the decryption is failing?<br><br>Thanks,<br>
