This week I have been working with the video guys to get our Tandberg VCS system integrated to OCS. We have had mixed success so far with call control working but media failing when calling from OCS to Tandberg. We are waiting on Tandberg to take a look at some of our log information to see if they can shed any light on it for us. Personally, I think we need to move our version on the VCS to 4.1, which I believe, may solve some issues and make the integration work a little better. This may take some time to accomplish but for now, we are stuck with our limitations. Although TLS seems to work no problems, SRTP is an issue for the Tandberg side of the house no matter what version of VCS but I have heard a rumor that there is a fix on the way for this.
I had hoped that this integration was going to be a little tighter and easier to get working but it is what it is right now. This is an interesting thread from a VTC forum that I can echo some of the setup problems with this integration. I will update this post when I get any further.
