When we have the same SS account registered on a number of devices and an incoming call is answered on one device, every other device will show this as a 'missed call', even though it was answered, just not on those particular units. Someone on Whirlpool (http://whrl.pl/Rd9mwj) suggested this:
They should be sending a cancel message with a "call completed elsewhere" reason code and the call should not be logged as a missed call at any handset.
I never realised that this solution was technically possible and am still not convinced that it is. What is your opinion? I mean, it would be awesome if this could be implemented but I am not getting my hopes up.
