The phone supports an optional automatic off-hook call placement feature for 

each registration.
Configuration changes can performed centrally at the boot server:

The purpose of hold is to pause activity on one call so that the user may use 

the phone for another task, such as to make or receive another call. Network 

signaling 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.
Configuration changes can performed centrally at the boot server or locally:

Configuration file: 
phone1.cfg

Specify which registrations have the feature and what contact to call 
when going off hook.

Configuration file:

Specify whether RFC 2543 (c=0.0.0.0) or RFC 3264 (a=sendonly or 
a=inactive) outgoing hold signaling is used.
