Don't diss skype until you've tried skype for business
The presence model of Skype for business is more like rolling a dice. often i receive an email telling me I missed a conversation when i've been online the whole time, then when I log onto the outlook web app on my home laptop a week later, the conversation appears there instead. if you happen to have S4B open on both laptop and phone, you will only get notifications to none-or-one of those devices, and it's totally random which one.
etc. etc. etc. </rant>
