FaceTime Audio Time Freeze
Ever since I have updated to Yosemite, mainly happening more during 10.10.3, My FaceTime audio calls have consistently frozen
The call essentially drops out, however rather then hanging up the call the time on the FaceTime window will say the duration of the call up until it froze.
For example, I was on a call last night and continues talking there for a while before realising the call had frozen at 1:35:37 so as a test I left it there for 20 minutes to see if it caught up, it didn't and just remained frozen, the only fix was to hang up and try again, only to have it happen again later.
It has no reason to drop out as we both do not have any other applications open or anything and yet does this quite often, I'm not sure if its an issue in the software but from searching around on the forums I don't seem to see any solution to my problem so far, so any help would be much appreciated.
MacBook Pro, OS X Yosemite (10.10.3)
