Encryption of video calls
Hello...
I have a question about video encryption endpoints. I use a SX80 to call a MX300. When I unsubscribe from our 10.5.2 CUCM and H.323 allows to establish a the call is successful and I get a pop up "encrypted call."
When I enter them on the CUCM as SIP endpoints and try to make a call I get 'impossible to establish the encrypted call' and the call fails. Our CUCM is in unsafe Mode, but he says that he has supported for TLS and SRTP encryption 256 and 128. If I put the two end points to Besteffort the call goes through but I get the pop up "unencrypted call.
It must be in mixed mode for all encrypted sessions?
Any help is appreciated.
The CUCM must be in mixed mode for secure communication. (See guides attached below for the required reference parameters and config.)
Cisco TelePresence management endpoints TC on CUCM 10.5.1 (TC7.2)
(p.11)
* NOTE *.
- CUCM must operate in mixed mode for secure communication.
- You must define a security profile of device for each type of endpoint.
- If you want to allow several modes for the same type of endpoint authentication, you must set up a profile for each mode.
- See the Safety Guide of CUCM for more information:

can I video call through facebook, using the browser firefox web?
My wife just bought a tablet... and there was a facebook application in the Tablet, but I can not video call...
Whenever I'm doing video call, he said: "inaccessible".So, I thought that if we do this on the browser as normal video call from PC to PC using firefox, then it would do (?).
Anyone tried?
Sites like Facebook are not designed to make video calls on the browsers, it's where there are apps for that. However, there are a simple HTML5 Web sites offering video lectures/talks in which will work with browsers on tablets.
Please note we only provide support for the Firefox browser and not 3 third-party sites or applications, these problems or questions, address them.
However, as part of my effort to help, the person that you can try to reach through the Facebook app can't equipped with software to manage your call to them or that they are not online when making your call, giving you this error. It is also important to check that you are connected to the internet with a strong link to avoid problems with video calls. You can try the Google search why you might encounter such problem with Facebook or see if restarting your device can help.

Hello
The people who answer questions here are for the most part, other users Firefox dedicating volunteer their time (like me), not employees of Mozilla or Firefox developers.
If you want to leave a comment for the developers of Firefox, you can go to the Firefox help menu and select submit comments... or use this link. Your comments gets collected at http://input.mozilla.org/, where a team of people read it and collect data on the most common questions.

Hello
My problem is this: when I start calling with my girlfriend my cam just freeze and stop recording. Problem is, it's hapenning only, when I call with GF. I tried to call someone else, and my camera works perfectly. Skype detects camera all the time in the settings. GF camera works properly and we can hear each other, but she can't see me.Strange, that is, that the problem just appeared one day. We were video calling each other on a daily basis. No common solution on the help page does not seem to help.
Advice, tips or tricks?
EDIT: DxDiag.txt added
I've updated Windows, but it solves the problem.
With the new camera, everything works perfectly.
Thank you very much for the help. I appreciate it.

Video calls on Chromebooks?
Is this to come at all? I'm going to buy my parents a Chromebook (it's just easier for them) and if it is not a way for them to make the video calls via Skype on that OS so I have to transtition them on Google Hangouts. I'd rather not (they're old and set in their ways) but the ease of Chromebooks > using Skype any day.
I hope that there is a timetable for this?

When Im video calls what I'm saying is displayed as a text next to the screen. So when I finished and go to messages the whole conversation video call is in the form of a written message, but as a very bad translation! How can I stop this time while Im making the call and appeared subsequently?
Turning off translation will probably help

Somehow restart in Windows safe mode helped.How it happened I don't know and is not important, that I will accept the reboot in SafeMode as a solution when Skype is bad conduct.
