Title
In this chapter it will be covered both Telephony Conversation Capabilities and
TelephonyConversationStates. They are very important because they can tell, what we can and what can't be done
with TelephonyConversation, as well as whats going on with active conversations.
Capabilities
Telephony Conversation Capabilities can tell what we can and can't be done
with TelephonyConversation. It is recommended that they are bound to UI elements (Usually buttons}. These
elements should be disabled if specific capability is set to false or enabled if capability is set to true. This is
crucial because performing action like conversation.end() without
capabilities.canEndCall set to true will throw a
CapabilityMissing error. In the snippet below it will be shown how to retrieve
capabilities.
var conversation;
// ...
// Retrieve conversation object from conversation event.
// ...
var conversationState = conversation.states;
We'll cover specific capabilities in upcoming tutorials.
States
Telephony Conversation State can tell, if conversation is put on hold or not,
or if screen share is being received from remote participant. In the snippet below is shown how to retrieve conversation
states.
var conversation;
// ...
// Retrieve conversation object from conversation event.
// ...
var conversationState = conversation.states;
Specific states will be covered in upcoming tutorials.
