Hello,
I'm installing cisco meeting server scalable and resilient deployment.
I have 2 WAN networks: Internet and second network, something like the Internet (with NAT configured on it). This networks can't communicate with each other.
I've installed 2 cms edge servers with webbridge, loadbalancer, turn. One server is for clients on Internet, the second one for clients in my second network.
I've turned on 2 my turn simultaneously and have a problem with that because my webrtc clients on Internet could choose turn in my second network and my clients in the second network could choose turn on the Internet and they can't send video/audio traffic to the right turn.
Which cms service can decide, which turn to use for webrtc client? I haven't got problems with the application, because, I think, application decide which turn to choose.
Can I configure webbridge to choose which turn to use?
Best regards,
Uladzimir Hryharovich

If running CMS 2.1 and later, you can use the API to specify the Call Bridge that is associated with the TURN server. You could specify the Call Bridge that is associated to the public Web Bridge to use the public TURN server.

Hello Patrick,
Thanks a lot for your answer.
But I have 2 callbridges in a cluster for redundancy and think if I configure first of them to use TURN server for my first public network and configure the second callbridge to use TURN server for my second public network, I lost my redundancy. Is it true? Can I somehow save my cluster redundant configuration and configure TURN servers?

I'm not 100% sure it would work, but could you use split DNS? i.e. use the same DNS name for both TURN servers, but have it resolve differently depending on which network it's in? This would of course require the users and CMS's in each network to be using different DNS servers.

Take a look at the following CMS Configuration Guides:
You could use the same certificate for more than one CMS component, or use individual certificates, this is mentioned in the certificate deployment guide.

You add CMS just as you would add any other managed system to TMS, add it using the address you use to access the web interface, you can find directions and configuration steps in the TMS 15.3 Release Notes and TMS Admin Guides.

use callbridge grouping. and put each turn and Webbridge server part of that callbridge group. this way you would force the users to use that particular turn server.
by the way, if callbridge ip is reachable. then turn isnot used. it is only used when there is a NAT.
another point to note is, when ever you put 2 webbridges, DUAL homing issue appears. you must use a loadbalancer HAproxy or F5 etc with persistent cookie insertion or source IP hash algorithm which will force the users to stay connected when http session refreshes.
