14.2.5.9. SIP Subscriber as DSS Key on a Desktop Phone 
Feature Description
It is possible to configure a SIP subscriber as a DSS key (DSS destination)
on a desktop phone with AMO ZIEL.
Scenarios
The busy condition of the SIP subscriber is displayed via a LED on
the monitoring extension's DSS key LED.
- LED off: SIP subscriber is free to get a call.
- LED on: SIP subscriber is busy.
If SIP subscriber is member of an ONS group
- If the SIP subscriber is the master of the ONS group, the DSS LED shows the status of the ONS group.
- If the SIP subscriber is the slave and the slave number is monitored, the DSS LED shows the status of the slave.
SIP subscriber is called if free (LED off) when the DSS key is pressed
on monitoring extensions.
Remarks
- The ringing state of the SIP subscriber is considered as busy, therefore the DSS LED does not flash and call pickup is not possible.
- Local features activated on a SIP subscriber cannot be monitored by the system. Call forwarding locally activated on the SIP subscriber will be executed when the DSS key configured with the SIP subscriber as destination is pressed.
