/mcpCisco Unified IP 7931G Phone Interaction You can configure Cisco Unified IP 7931G phones in two modes: • NoRollOver • RollOver (across the same DN or across different DNs) When Cisco Unified IP 7931G phones are configured in NoRollOver mode, they operate like regular phones that are running SCCP, and in this mode transfers or conferences cannot occur across the different addresses. JTAPI will support controlling and monitoring of a 7931G phone when it is configured in NoRollOver mode. In RollOver mode, Cisco Unified IP 7931G phones support transfer or conference across different addresses. In this mode, JTAPI does not allow controlling and monitoring of a Cisco Unified IP 7931G phone. Applications see such terminal/addresses as restricted. If a Cisco Unified IP 7931G phone is in the control list of an application user and the phone configuration changes from NoRollOver to RollOver mode, JTAPI sends a CiscoAddrRestrictedEv event for addresses on the Cisco Unified IP 7931G phone and sends a CiscoTermRestrictedEv for terminals, with cause CiscoRestrictedEv.CAUSE_UNSUPPORTED_DEVICE_CONFIGURATION. However, if the phone configuration changes from RollOver to NoRollOver mode, JTAPI sends a CiscoAddrActivatedEv event for addresses on the Cisco Unified IP 7931G phone and sends a CiscoTermActivatedEv for terminals. If a Cisco Unified IP 7931G phone that is configured in RollOver mode transfers or conferences to JTAPI-controlled addresses, JTAPI applications do not recognize a common controller in the final and the consult call. This would provide different behavior to the JTAPI application. Depending on how the JTAPI application is processing information that is provided in events, applications may require changes to handle JTAPI events for this transfer or conference scenario. You can disable transfers and conferences across the line by configuring the Cisco Unified IP 7931G phone to NoRollOver mode through the phone configuration window of Cisco Unified Communications Manager Administration. There are two new cause codes for the CiscoRestrictedEv interface. When the terminal or address is restricted because a Cisco Unified IP 7931G phone is configured in RollOverMode, JTAPI sends CiscoAddrRestrictedEv with cause CiscoRestrictedEv.UNSUPPORTED_DEVICE_CONFIGURATION. This release also introduces a default cause code CAUSE_UNKNOWN, which applications should handle. Backward Compatibility This feature is backward compatible. You can disable this feature by configuring all Cisco Unified IP 7931G phones in a cluster in NoRollOver mode or by not having any Cisco Unified IP 7931G phones in a Cisco Unified Communications Manager cluster. If any phone in a Cisco Unified Communications Manager cluster is configured with RollOver mode, it may cause changes to the behavior of JTAPI-controlled addresses and terminals.
