/mcpTerminal to getUniqueID API. UniqueID may or may not be the same for different shared lines depending on the scenario. The application can query the uniqueID corresponding to each shared line on receiving TermConnActiveEv for that shared line Terminal. Whenever the uniqueID changes, JTAPI delivers CiscoConnectionUniqueIDChangedEv to the call observer of the application. As of Release 8.0(1), there is no supporting use case where JTAPI delivers CiscoConnectionUniqueIDChangedEv event to the application. Note Interface Changes CiscoConnection, on page 386, CiscoConnectionUniqueIDChangedEv, on page 399. Message Sequences End to End Call Tracing, on page 904 Backward Compatibility This feature is backward compatible. EnergyWise Deep Sleep Mode This feature allows the phone to participate in an EnergyWise enabled system. The phone reports its power usage to a EnergyWise compliant switch to allow the tracking and control of power within the customer premise. The phone provides alternate reduced power modes including an extremely low, off mode. The Cisco Unified Communications Manager administrator configures and exclusively manages the phones power state through vendor specific configuration on the Cisco Unified CM Admin pages. When the phone turns off power after negotiation with an EnergyWise switch, it unregisters from Cisco Unified CM and enters Deep Sleep/PowerSavePlus mode. Phones automatically re-register back with the Cisco Unified CM once the Deep Sleep mode configured PowerON time is reached. However, you can press the ‘select’ key on the Cisco Unified IP Phones Series 9900 and 6900 while in Deep Sleep/PowerSavePlus mode to wake up the phone, these phones automatically power on and re-register back with the Cisco Unified CM. However, for Cisco Unified IP Phones 7900 Series phones, you can neither power on nor re-register back with the Cisco Unified CM during Deep Sleep/PowerSavePlus mode unless the ‘PowerON’ time is reached. You can configure Deep Sleep mode on the Device page of the Cisco Unified CM. Configure Deep Sleep mode for the phones at least 10 minutes before the actual power off time to allow the information to synchronize between the switch and the phone. The Power off idle timer enables only in the case when there is physical interaction on the phone. For example if there is a call on the EnergyWise configured phone during the deep sleep time and the user tries to disconnect the call from the application, then the power off idle timer defaults to 10 minutes but if the user disconnects the call manually from the phone, then the power off idle timer takes the value configured on the Cisco Unified CM device page. When a terminal unregisters from Cisco Unified CM, JTAPI exposes CiscoProvTerminalUnRegisteredEV event to application with a new reason “CiscoProvterminal UnRegisteredEV.ENERGYWISE_POWER_SAVE_PLUS”.
