3.2 Call Management Features
3.2.1 Automatic Off-hook Call Placement
The phone supports an optional automatic off-hook call placement feature for each
registration.
3.2.2 Call Hold
Call hold is a fundamental feature of the phone. The purpose of hold is to pause activ-
ity on one call so that the user may use the phone for another task, such as to make or
receive another call. Network signalling is employed to request that the remote party
stop sending media and to inform them that they are being held. A configurable local
hold reminder feature can be used to remind the user that they have placed calls on
hold.
