/mcpClick to Conference The Click to Conference feature enables users to create conferences from an Instant Messaging (IM) application without creating a consult call first. The Cisco TSP treats the feature as an existing conference model; however, when the conference is created or dropped, the CtiExtendedReason may come as Click2Conference. Interface Changes None. Message Sequences See Click to Conference, on page 546. Backward Compatibility This feature is backward compatible. CCMEncryption Enhancements Starting with release Unified Communications Manager 10.0(1), Encryption method, which is used to encrypt the user login password, is enhanced. Older CiscoTSP clients (9.x or earlier) use Symmetric Key Encryption. Starting with rlease 10.x, the CiscoTSP client is enhanced to use a combination of Asymmetric and Symmetric Encryption mechanism. This enhancement provides more security for user credentials in non-secured connections. Cisco recommends that applications/users upgrade Cisco TAPI clients to take advantage of this security enhancement. To maintain backward compatibility from CTI, a new CTI Service Parameter is introduced - Require Public key Encryption. The default value for this Service Parameter for this Release is False. On False: CTI/CUCM allows applications/CiscoTSP clients using symmetric encryption method and Asymmetric Public key encryption method to connect with CUCM. On True: Only CiscoTSP clients/applications which use asymmetric PublicKey Encryption Method will be able to open provider with Unified Communications Manager 10.x. Cisco recommends that applications upgrade Cisco TAPI clients and set this service parameter to "true". The proposed plan for future releases is to set default value as true for this service parameter and later deprecate it to ensure that applications do not use older CiscoTSP Clients which use Symmetric Encryption method. Interface Changes There are no interface changes for this feature.
