/mcpMessage Sequence No effect on the message sequence Backward Compatibility No backward incompatible changes Version Format Change In release 6.0, the Cisco Unified JTAPI version changed from a 4-digit format to a 5-digit format that is similar to the format used by Cisco Unified Communications Manager. The JTAPI version will remain similar to the Cisco Unified Communications Manager version. New interfaces let applications get the extended version number. See CiscoJtapiVersion, on page 261. Backward Compatibility This feature is backward compatible. Verification Involving PSTN Reachability The Verification Involving PSTN Reachability (VIPR) feature routes calls that are currently routed over PSTN, over the internet. For a normal VIPR call, JTAPI supports a VIPR call but no notification is sent to the application indicating that it is a VIPR call. Currently, VIPR calls are similar to Gateway or ICT calls. When the quality of VIPR calls over an IP trunk drops below a certain threshold, the calls are automatically routed through PSTN. JTAPI supports this fallback but does not report this to applications. Whenever VIPR PSTN fallback happens, media is terminated and reestablished. Applications can view CiscoRTPInputStoppedEv, CiscoRTPOutputStoppedEv followed by CiscoRTPInputStartedEv and CiscoRTPOutputStartedEv indicating the same. Interface Changes There are no interface changes. Message Sequences See Verification Involving PSTN Reachability, on page 1583. Backward Compatibility This feature is backward compatible. Video Capabilities and Multi-Media Information In Cisco Unified Communications Manager 10.0(1), JTAPI is exposing video capabilities for supported terminals and calls. Video capabilities for near and far-end terminals include whether they are video-enabled, inter-operability with TelePresence, and the number of screens. Video attributes for calls will also be available to JTAPI applications which would include IP/port address, codec, and other information.
