/mcpInteraction Feature When a switch initiates a call transfer between two segments that have the same precedence level, the segments maintain the precedence level upon transfer. When a call transfer is made between call segments that are at different precedence levels, the switch that initiates the transfer marks the connection at the segment that has the higher precedence level. Cisco Unified Communications Manager supports this requirement by upgrading the precedence level of a call leg that is involved in a Call Transfer operation. For example, party A calls party B with Priority precedence level. Party B then initiates a transfer to party C and dials the Flash precedence digits when dialing. When the transfer is complete, the precedence level of party A gets upgraded from Priority to Flash. The Call Transfer feature is enabled automatically when MLPP is enabled, and the phones support the Transfer softkey. Note The precedence level upgrade does not work over a trunk device such as an intercluster trunk (ICT) or a PRI trunk. Multilevel Precedence and Preemption (MLPP) Call Transfer Restrictions Restriction Feature Logical partitioning handling does not take place when both the transferred and the transferred destination devices are VoIP phones. Logical partitioning handling does not take place when geolocation or a geolocation filter is not associated with any device. Logical Partitioning To restrict transfer for external call scenarios, see the “External Call Transfer Restrictions” chapter. External Call Transfer Restrictions If a call transfer to a hunt pilot is initiated when an announcement is in progress, the call is redirected only after the announcement is complete.
