I have both a Unidata and Cisco phone for BYOD. About 50% of the time, when I receive a call I answer but there is no audio. There is no audio on the other end either. I can make outgoing calls just fine on both devices and the incoming calls work fine the other 50% of the time. Does anybody have any suggestions? I can sit by a landline and call my phone 5 times after this happens to try and diagnose the issue but everthing works then someone else calls again an hour later and I have the issue. Thanks for any assistance.
