When Client has not connected to Server for long time. When the large amount of calls is on PBX even though it has not been so long time since Clientconnected to Server last time.To make Client start faster, it is highly recommended that Client connects to the Server often, or the Client maintainsa connection to the Server during high-call times.4.2.
