I have Onex running on a UCM, all software and firmware matched at 9.0 SP4. We use the voip mode and everything works perfectly both inside and outside the corp.network except one tiny issue that I can't seem to solve. When playing back voicemail from the mobile app, user clicks on the message and it opens and starts playing but stops after one second. Then we press the pause button and then the play button and it plays normally. We can then rewind and replay the full message. If we go back to the home button and then open voicemail again, the same thing happens. This only started after upgrading to 9.0. It is on all iPhones and all accounts. It is on new messages and old messages. Does anyone have this problem and found a fix or is this a bug in 9? Thanks
