An additionrestriction requires that at most one other Connection may be in eitherthe INPROGRESS state or ALERTING state. The Provider must also beIN_SERVICE.

This Connection isin the IDLE state and is the return value for this method. Thepost-conditions which are true when this method returns are as follows,where 'c' is the returned connection.<p><OL><LI>(call.getProvider()).getState() == IN_SERVICE<LI>call.getState() == ACTIVE<LI>c.getState() == IDLE</OL><p>⌨️ 快捷键说明
