Skype to Polycom content Sharing Fails After Upgrade to SFB Service pack 2
Customer expereienced issues where content failed to start or delayed starting up to ~5 minutes after upgrading to Skype for Business service pack 2.
Microsoft engineer and I found TLS problems between DMA and SFB CU2 after the upgrade. New certs were issued for the DMA that included SANs for the focus uri and pool. See http://drlync.blogspot.com/2016/02/certificate-error-from-polycom-dma-7000.html
