|The VCS Modules / Call|
If you are in a cellular call and you receive a Vocera call or are asked to join a broadcast or instant conference, the behavior of the VCS app depends on the type of device that you are using and its operating system version.
For Android devices running version 8.x or later, you must end the cellular call before answering the incoming Vocera call, broadcast, or instant conference. For Android devices running a version prior to 8.x, the cellular call automatically ends if you answer the incoming Vocera call, broadcast, or instant conference.
If you are in a Vocera call and receive a cellular call, the Vocera call is placed on hold until the cellular call is complete, and is then resumed.
