/mcp• Update Cisco Unified TSP whenever a different version (higher version than the existing version) is available on the Unified Communications Manager server. • Update Cisco Unified TSP whenever a QBE protocol version mismatch exists between the existing Cisco Unified TSP and the Unified Communications Managerversion. CIUS Session Persistency Wireless devices introduced by Cisco such as CIUS have the capability to move between WiFi networks and also across WiFi and VPN networks (over 3G/4G) and still retain their registration with the same CiscoUCM. However, due to the change in the network the IP address of the device might undergo a change. The same scenario is applicable for docking and undocking of the CIUS phones. To indicate this change in IP address of wireless devices such as Cius, TAPI will expose the changed IP address for lineDevices and phoneDevices through DEVCAPS structure. TAPI will send notification to Applications on change in IP Address information on lineDevices of CIUS Device. LINE_DEVSPECIFIC notification is fired on all Open lines on a CIUS Device. TSP would fire LINE_DEVSPECIFIC event with param1 = SLDSMT_LINE_PROPERTY_CHANGED,param2 = LPCT_DEVICE_IPADDRESS. TAPI will send notification to Applications on change in IP Address information on phoneDevices. PHONE_DEVSPECIFIC notification is fired on the phoneDevices. TSP would fire PHONE_DEVSPECIFIC event with param1 = CPDSMT_PHONE_PROPERTY_CHANGED_EVENT, param2 = PPCT_DEVICE_IPADDRESS. TAPI will expose the changed IP address, IP Addressing Mode (IPv4, IPv6) of lineDevices in the devspecific data of LINEDEVCAPS when lineGetDevCaps API is invoked with Extension version 0x00090001 or higher. TAPI will expose the changed IP address, IP Addressing Mode (IPv4, IPv6) of phoneDevices in the devspecific data of PHONEDEVCAPS when phoneGetDevCaps API is invoked withExtension version 0x00090001 or higher. CIUS devices are SIP end points and like all other SIP end Points, they currently don't support IPV6. Note Interface Changes No interface changes.
