I had just written about the age of my IMac maybe being too old...
but something very interesting just happened.....I DID NOT change any settings
I have not been able to place any outgoing calls...all tried and failed...
up to now I have not tried receiving a call..... I just had someone call me on my Iphone 5S and I received
it perfectly through the Imac...
then I tried making numerous outgoing calls through the IMac and now every one worked fine....
not sure the reason
its almost like when I first received one of the original IPads years ago....could NOT get onto my Wifi network at home, spoke to
Apple and they told me to go over to McDonalds and try to get on their Network and if that worked come back home and retry and
everything has worked fine ever since that day
