H.235
Yealink video conferencing systems support H.235 128-bit AES algorithm using the
Diffie-Hellman key exchange protocol in H.323 calls. To use H.235 feature for H.323 calls, the
participants in the call must enable the H.235 feature simultaneously. When a site places a call
on the H.235 feature enabled system, the system negotiates the encryption algorithm with the
destination system.
The H.235 parameter on the system is described below:
Parameter Description Configuration Method
