Configuring Your System

Multiple Line Keys per Registration

More than one Line Key can be allocated to a single registration (phone number or line) on SoundPoint IP phones. The number of Line Keys allocated per registration is configurable.

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

Central	Configuration file:	Specify the number of line keys to assign per registration.
(boot server)	phone1.cfg	• For more information, refer to Registration <reg/> on page A-107.
Local	Web Server	Specify the number of line keys to assign per registration.
	(if enabled)	Navigate to http://<phoneIPAddress>/reg.htm
		Changes are saved to local flash and backed up to <Ethernet
		address>-phone.cfgon the boot server. Changes will permanently
		override global settings unless deleted through the Reset Local
		Config menu selection and the <Ethernet address>-phone.cfgis
		removed from the boot server.
	Local Phone User	Specify the number of line keys to assign per registration using the
	Interface	SIP Configuration menu. Either the Web Server or the boot server
		configuration files or the local phone user interface should be used to
		configure registrations, not a mixture of these options. When the SIP
		Configuration menu is used, it is assumed that all registrations use
		the same server.

Multiple Call Appearances

The phone supports multiple concurrent calls. The hold feature can be used to pause activity on one call and switch to another call. The number of concurrent calls per line key is configurable. Each registration can have more than one line key assigned to it (refer to the previous section, Multiple Line Keys per Registration).

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

Central	Configuration file:	Specify the default number of calls that can be active or on hold per
(boot server)	sip.cfg	line key.
		• For more information, refer to Call Handling Configuration <call/>
		on page A-64.
	Configuration file:	Specify per-registration the number of calls that can be active or on
	phone1.cfg	hold per line key assigned to that registration. This will override the
		default value specified in sip.cfg.
		• For more information, refer to Registration <reg/> on page A-107.
