设备端拨号并立即forceHangup()，event异常？
设备端拨号之后，callPageOnShow2秒，马上调用forceHangup()挂断，event如下，endVoip会有2次。finishVoip之后就不要再有event了。必现的。 sourceData: {"eventName":"callPageOnShow","status":"","keepTime":""} sourceData: {"eventName":"cancelVoip","groupId":"wxf830863afde621ebWmpfVoip6031637812064499742","status":"forceFromApp","keepTime":""} sourceData: {"eventName":"endVoip","groupId":"wxf830863afde621ebWmpfVoip6031637812064499742","status":"","keepTime":0} sourceData: {"eventName":"finishVoip","groupId":"wxf830863afde621ebWmpfVoip6031637812064499742","status":"","keepTime":0} sourceData: {"eventName":"joinFailListener","groupId":"","status":"","keepTime":""} sourceData: {"eventName":"endVoip","groupId":"","status":"","keepTime":0}
