AE Services supports WTI (Web Telephony Interface) Service which provides integration with enterprise applications through REST services. These services expose core telephone functionality and provide access to third party call control features on Communication Manager. The Telephony REST Service provides a high-level interface for basic call control services, simplifying traditional CSTA based call control. Applications need to maintain a bearer token to manage their session on the server and do not need to track call state or information.

The Telephony REST Service also supports third-party call control events corresponding to the API. It enables users to originate outbound calls and receive updates on the call progression. This service uses a session-based model where sessions can be explicitly created by sending a create session request using session APIs with credentials. The service uses the DMCC TSAPI Service to perform most of its requests, which requires Computer Telephony Adjunct Links to be licensed on Communication Manager and a TSAPI Basic license (denoted as TSAPI Simultaneous Users in the license file) for each device in use concurrently by the Telephony REST Services.

From AE Services Release 10.2, WTI service provides APIs corresponding to all the APIs provided by DMCC.
