Release 5.2.1

Avaya Aura® Application Enablement Services (AE Services) Release 5.2.1 was made generally available in January 2010. This is NOT the latest AE Services release; the latest release is recommended for new development.

New In This Service Pack

The Service Pack release resolves a number of issues, including:

  • TSAPI Client:
    Erroneous error messages are no longer displayed when reconfiguring the Log to File option of the TSAPI Spy application.
  • TSAPI Server:
    The TSAPI Service now always reports the correct event cause in the CSTA Retrieved event.

For detailed information about this release, see:

Compatibility Information

Compatibility with AE Services Release 4.2 Applications

All TSAPI applications created with the AE Services Release 4.2.x SDKs and client libraries will work seamlessly on AE Services Release 5.2.1 without the need to recompile code and without the need to replace any third-party library components.

Note: AE Services 4.2 DMCC applications must specify the 4.2 or earlier protocol version. If a protocol version is not specified, the server will default to 5.2 and the application may receive unexpected XML messages with added elements and/or receive new XML messages.

Note: The Avaya Aura AE Services 5.2.1 TSAPI SDK is not available for download. DevConnect members can order the TSAPI SDK via the Procurement option.
