We've 3 CMS in our deployment and one DNS record for CMA . DNS record is pointing three ip adresses of our CMS. In case of failover (CMS1 down) , DNS still solve first CMS (CMS1) and it's failing. If we type "ipconfig /flushdns" to clear dns records on client computer , DNS start to solve second CMS(CMS2). Is there any way to solve other DNS records (CMS2 ,CMS3) without typing "ipconfig /flushdns" on client computer ?
To find a Web Bridge, the browser performs a DNS A record lookup on the Web Bridge URI specified, for example join.example.com. In deployments with multiple Web Bridges, the result of this could be multiple IP addresses. Unless a policy is in place, the browser can pick any of the DNS A records and switch between them during a session . This may result in the Web RTC clients rehoming across Web Bridges and causing connections to drop. The consequence of this will be that the user has a very poor user experience during the conference, with the call repeatedly dropping.
I recommend you to use load balancer. DNS A should points to a single balancer's IP address. Don't forget to increase sticky timer for user's sessions.
