Hi, please help us. The Avaya IP Office has a very nice feature, this is the Mobile Twinning: - if there is an answered call for example on the deskphone but the client wants to leave the office, then he would like to move the active call from the deskphone to his mobile device. And the extra is in this that the deskphone and his mobile phone are same extensions. If comes a call these phones are ringing together. And this feauture works inversely, so if the client arrive his desk, he can move the call with one click from his mobile to his deskphone as well. Can we make this with 3CX as well? How does it work? Now we compete with Avaya, and the client want this funkction, so it is very important for us. Thanks a lot.
