You can call any participant of a conversation or group chat that you are in.
Vina places the call to the participant that you have selected. In this call, tap Vocera to return to the conversation:
The conversation now includes a record of the call, indicating whether you successfully placed or received the call, or whether the call was missed.
If the user that you are trying to call has made himself or herself unavailable, the call icon on this screen is red.
You can tap this icon to make an urgent call to this user if the group to which you belong has been granted permission to make urgent calls.
