Call API Reference

The following is a list of methods available in Call API. The Call object is created by calling MesiboCall.call() or mesibo creates for you in an incoming call as explained in Overview.

Initialization Functions

It takes the following parameter:

mCall.setListener(this);
// The InProgressListener is implemented in "this" context

Call Handling Functions

For example, in Android,

mCall.hangup();
