From now on an extended version of call control is available in Bubble! Besides being able to answer and end calls via a button in the pop-up notification, it is now also possible to transfer calls (announced and cold transfer), put them on hold and resume the call. In addition, the call control buttons have been given a visually clearer place in the pop-up notification. Wondering if your telephony platform has these new buttons? Then check out our compatibility list (click here) under the 'features' tab.
