Here’s a favorite Skype trick of mine. If I know I want to be able to walk around during a meeting, I’ll get Skype loaded up on my Android phone as well as my computer. When the call comes in, both devices ring. I can answer the call on either device. After, I can switch seamlessly, throwing the call back and forth between the two.
I’m not sure if it’s required to have the Android version up and running ahead of time, but I usually do it this way to make sure the call gets registered on the phone if I plan to answer it on the PC.
While in the call on the PC, I locate the call details on the Android device, and tap and hold. Then I can join the call. The call jumps to the phone and hangs up on the PC. The reverse works as well.
I’m not sure yet whether this would work if each device was on a separate network. I’ve only tried it with both on my home wifi.
