How it works
If you are signed in to Skype on multiple devices (a laptop, tablet and a smartphone) and you are sending chat messages to a group of friends from your tablet. Skype will only send new message notifications to your tablet and not to any of your other devices. All of your other devices will remain blissfully silent. You can continue to focus on the most important thing, your conversations, without being disturbed by the bleeping and buzzing from all of your other devices.
The moment you stop actively using Skype on any device, all devices will receive notifications again to make sure you never miss anything important. When you pick up any one of your devices to respond, we will stop send notifications to all other devices. Call notifications are still sent to all devices so you can answer on whichever gadget you prefer, not just the one you’re closest to.
Though the delivery of notifications is targeted and personalized to your own device usage, your chat history continues to sync across all devices allowing you to continue a conversation from any one of them.
Skype is rolling out the active endpoint enhancement over the next few weeks. You can download Skype for iPhone from the App Store for free.
