/mcpIntercom Interactions Interaction Feature The Unified Communications Manageradministrator can use the Bulk Administration Tool to add many intercom users at once instead of adding users individually. For more information, see Bulk Administration Guide for Cisco Unified Communications Manager. Bulk Administration Tool When the intercom destination is a barge target, the Cisco Unified IP Phone can still support whisper intercom. When the destination caller chooses to talk to the intercom caller by pressing the intercom button, the original call is put on hold, and the barge initiator is released. Barge The intercom call will override DND on the destination phone. Do Not Disturb (DND) When a call is preserved, the end user must hang up before the phone can reregister with Unified Communications Manager. When the intercom call is in whisper mode, it represents a one-way medium, and the terminating side might have no user at all; therefore, only the intercom call in talkback mode will get preserved. (Whisper intercom will not get preserved.) Call Preservation When Cisco Unified IP Phones register with SRST, the phones do not register intercom lines; therefore, the feature will not be available when the phones are registered with SRST. Cisco Unified Survivable Remote Site Telephony (SRST) With the Unified Communications Manager Assistant Configuration Wizard, Cisco Unified Communications Manager Assistant configuration takes less time and eliminates errors. The partitions, calling search spaces, route point, and translation pattern automatically get created when the administrator successfully runs and completes the configuration wizard. Cisco Unified CommunicationsManager Assistant You can use CTI/JTAPI/TSP to set or modify the preconfigured target directory number for an intercom line. You will receive notification if the target directory number is updated or reconfigured through Cisco Unified Communications Manager Administration. Be aware that CTI/JTAPI/TSP is backward compatible if the intercom line is not configured to be controlled by the application. If the intercom line is configured in the application user list, you may have to make changes and test the compatibility. CTI The intercom feature interacts with Cisco Extension Mobility. The system presents an intercom line to a user who uses Cisco Extension Mobility to log in to a phone that supports the feature if the device profile that the user uses to log in has an intercom line that is provisioned. The phone must be the default device for that intercom line.
