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:
Shared Call Appearances
Calls and lines on multiple phones can be logically related to each other. A call
that is active on one phone will be presented visually to phones that share that
call appearance. Mutual exclusion features emulate traditional PBX or key
system privacy for shared calls. Incoming calls can be presented to multiple
phones simultaneously. This feature is dependent on support from a SIP
server that binds the appearances together logically and looks after the
necessary state notifications and performs an access control function. For more
information, refer to Shared Call Appearance Signaling on page B-10 .
Central
(boot server)
Configuration file:
sip.cfg Specify the default number of calls that can be active or on hold per
line key.
• For more information, refer to Call Handling Configuration <call/>
on page A-55 .
Configuration file:
phone1.cfg Specify per-registration the number of calls that can be active or on
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-84 .
Local Web Server
(if enabled)
Specify the default number of calls that can be active or on hold per
line key and the number of calls per registration that can be active or
on hold per line key assigned to that registration.
Navigate to http://<phoneIPAddress>/appConf.htm#ls and
http://<phoneIPAddress>/reg.htm
Changes are saved to local flash and backed up to <Ethernet
address>-phone.cfg on the boot server. Changes will permanently
override global settings unless deleted through the Reset Local
Config menu selection and the <Ethernet address>-phone.cfg is
removed from the boot server.
Local Phone User
Interface Specify per-registration the number of calls that can be active or on
hold per line key assigned to that registration using the 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.
