IP Phone Administrator Guide

The phones have a parameter, “action uri disconnected” that allow a disconnect 
event to occur when the phone transitions from any active state (outgoing, 
incoming, connected, or calling) to an idle state. This parameter can use the 
variable “$$LINESTATE$$”.

If the Administrator enables this feature (by specifying a disconnect URI), 
when a call is disconnected, the phone 

checks to see if the event has a 

Disconnect URI configured. If the phones finds a configured URI with a 
$$LINESTATE$$ variable, it replaces the $$LINESTATE$$ variable with the 
appropriate line state of the current active line. After all of the variables are 
bound, the phone executes a GET on the URI. The following table lists the 
applicable values for the $$LINESTATE$$ variable.

The Action URI Disconnect feature allows an Administrator to determine the 
reason for the disconnect if required.

The $$LINESTATE$$ variable is optional and not required when 

enabling the “action uri disconnected” parameter.
