My client uses a Sametime Proxy and Sametime meetings for Web Audio/Video meetings using HTTPS. No problem about this, if you have acquired from Verisign or another Certified Authority.

But if you use a private ssl key, browsers like Mozilla and Chrome, block to install add-ons. Is the same situation as a self-signed certificate.

To avoid this you can use an alternate site for Sametime Web Player using only http.

2) Go to Sametime System Console -> Sametime Servers -> Sametime Proxy Servers and select your Sametime Proxy Server
