After 9.3 release random warble on a few of our Polycom VVX500
11-01-2017 USA-based account 2287 users 3800 DID lines - after last week's update to our POD, a few of our Polycom VVX500 are displaying a weird behavior --- the phone does a brief warble and calls are not getting through on those lines. I am logging the few reported instances today to see if it goes away. We have already unplugged these phones, leaving them off for a half hour and then restarting them. Only a few phones effected. If it continues, I will open a case. Anyone else see this on yours?
