Keep telephony applications connected to the call control layer with advanced TSAPI licensing for Avaya AES R5. This 1-year program is built for organizations that depend on stable CTI integration between business applications and Avaya voice infrastructure. By enabling advanced TSAPI access, the license supports the call-event visibility and control needed for contact center workflows, custom desktop integrations, and operational reporting. That matters when call handling cannot be left to generic interfaces or limited feature sets. Teams can maintain tighter alignment between telephony events and the applications that depend on them. This offering is suited to enterprise environments where integration reliability, licensing clarity, and vendor-backed support are part of the purchasing decision. It helps preserve continuity for existing Avaya deployments while giving IT and telecom teams a defined renewal path for advanced application connectivity.
