The held call still occupies the appearance button on which it was made or answered. A fast flashing green lamp is used to indicate held calls.
The caller hears music on hold. If your system does not have music on hold available, the caller hears double-beep tones every few seconds.
Calls that you leave on hold for too long return to your phone (when it is idle). The default return delay is 15 seconds, but can be changed by the system administrator. Returning calls ignore any forwarding or do not disturb settings.
If you have more than one held call, or one held call and a connected call, pressing the Conf soft key starts a conference between yourself and the calls.
