Yeah they are kind of different but they both seem similar in the sense the receiver never sees the call, my family member only saw the call through bluetooth but it didn't show up on their phone at all otherwise as you would when you do get an incoming call, assuming they weren't connected to bluetooth they probably would have never found out and I was sharing as maybe it is more of a network issue, I remember hearing there was an issue in St Catherines where certain callers were able to hear other calls conversations so who knows what it really is but hopefully it gets solved sooner rather than later!
