Mitel 6800 Series SIP Phone Release 4.2.0 SP2 Administrator Guide
5-303
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.
Example
If you enter the following string on Phone A for the “
action uri disconnected”
parameter:
action uri disconnected:
http://fargo.ana.mitel.com/disconnected.xml?state=$$LINESTATE$$
and then Phone A calls Phone B, Phone B answers and then hangs up, Phone A executes a
GET on:
http://fargo.ana.mitel.com/disconnected.xml?state=CONNECTED
which is what the remote server receives.
An Administrator can enable the disconnect feature using the configuration files or the Mitel
Web UI.
