Avaya Aura Application Enablement Services

Latest Release: 10.2 (Dec 2023)

Release 10.1.2

Avaya Aura Application Enablement Services (AE Services) Release 10.1.2 was made generally available in February 2023. This release introduces the Web Telephony Interface REST Service and includes an update to the DMCC .NET SDK, plus a number of updated product and developer guides. This is NOT the latest AE Services release; the latest release is recommended for new development.

IMPORTANT NOTICE AE Services 10.1 TSAPI and CVLAN Linux Clients and SDKs will only be supported on RHEL 8. AE Services 10.1 TSAPI and CVLAN Windows Clients and SDKs will continue to be supported on existing versions of Windows 32 and 64 bit OS. For more information, read the Product Support Notice.

New in Release 10.1.2

AE Services 10.1.2 includes the following new and enhanced features:

  • Real-Time Agent Event license type called Advance Agents, enabling third-party CTI applications to receive real-time updates for Ready, Not Ready, and Work Not Ready agent events. This new SDK and applicable Advance Agents licenses must be purchased from Avaya.
  • Introduction of the Web Telephony Interface service offering existing AE Services CTI interfaces as REST APIs, enabling cloud services and on-premises CTI applications to access CTI capabilities through these REST APIs to meet specific business requirements. The first set of APIs enables customers that use older Telephony Web Services (TWS) APIs to transition to REST APIs before TWS reaches end of support.
  • Support for Geo Redundant High Availability (GRHA) Virtual IP (VIP) configuration on the Azure platform.
  • System Manager Solution Deployment Manager and Solution Deployment Manager Client support the deployment and upgrade of an application using the OVA with the SHA256 hash algorithm.
