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. Users at the different locations have the ability to 

interrupt remote active calls.
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 

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.
