I have a DX80 connected to CUCM and when I receive a call from outside (via expressway) the video is not encrypted. Any ideas as to why? Devices connected to the VCS receive encrypted calls without issue. See call flow below:
External Entity > VCS-E > VCS-C > CUCM (9.1) > DX80
Solved! Go to Solution.
It is not. We have some downtime scheduled for next week. So looks like i will flip that switch then.
Thanks everyone for your input.
Not sure if you are aware, but please note that turning up mixed mode pre CUCM 10.0(1) is a little bit more involved that just flipping a CLI switch.
There are also some restrictions in older versions such as lack of Auto-registration support.
