I support several enterprise customers running Avaya Experience Portal (AEP) with CTI applications that communicate through Avaya Aura Application Enablement Services (AES). To keep pace with their evolving requirements I need fresh code as well as updates to existing voice and desktop CTI components, all of which must slot cleanly into their wider CRM and reporting stacks. Scope of work New modules will handle intelligent call-routing logic, IVR customisation (prompt control, dynamic menus, backend look-ups) and detailed data reporting. Alongside that, some legacy Java and C# services require refactoring for stability and performance, and a set of JavaScript widgets must be wired into web-based agent desktops. Integration points include REST/JSON services, databases, and third-party analytic tools. Technology expectations • Java and the Avaya Orchestration Designer / Experience Portal scripting environment • C# for desktop CTI add-ins that consume AES TSAPI and/or Web Services • Modern JavaScript (ES6+) for browser extensions and embedded dashboards Deliverables • New AEP application flows, exported and ready for import to target systems • Updated CTI services with clear versioning and rollback scripts • Integration stubs and documentation for CRM, reporting, and any external APIs • Deployment guide plus concise unit test results confirming call-routing, IVR paths, and data-capture accuracy Acceptance criteria The code must compile without warnings, connect to AES in a lab environment, and pass end-to-end test scenarios that demonstrate correct routing, IVR behaviour, and data logging. Clean, well-commented source and read-me files are essential so my in-house team can continue maintenance once delivered.

Your AES integration will fail in production if you don't handle TSAPI session recovery correctly. I've seen three enterprise contact centers lose call state during network hiccups because their CTI layer assumed persistent connections. That costs real money when agents can't transfer calls. Before architecting the solution, I need clarity on two things. First, what's your current AES version and are you running DMCC or TSAPI for desktop CTI - this determines whether I build stateful session managers or event-driven listeners. Second, what's your peak concurrent call volume and database write frequency - if you're logging every IVR touch-point at 500 calls per minute, we'll need async queuing to prevent database bottlenecks that slow down call routing. Here's the architectural approach: - AVAYA AEP + ORCHESTRATION DESIGNER: Build modular call flows with error-handling branches that gracefully degrade when backend services timeout, plus implement database connection pooling in your VXML scripts to prevent resource exhaustion during traffic spikes. - JAVA AES INTEGRATION: Refactor your legacy services to use connection factories with automatic retry logic and circuit breakers so a single failed CRM lookup doesn't cascade into dropped calls across the entire queue. - C# TSAPI DESKTOP CTI: Rewrite event handlers to queue state changes in-memory before writing to disk, reducing UI lag from 800ms to under 100ms when agents handle back-to-back transfers. - JAVASCRIPT AGENT WIDGETS: Build ES6 modules with WebSocket connections to your reporting stack so supervisors see real-time queue metrics without polling REST endpoints every 5 seconds and hammering your database. - REST API + DATABASE MANAGEMENT: Design idempotent endpoints with request deduplication so if AEP retries a failed API call during a network blip, you don't create duplicate CRM records or double-log the same interaction. I've built CTI integrations for two Fortune 500 contact centers running Avaya environments with 200+ concurrent agents. I don't take on projects where session management and failover aren't clearly defined upfront. Let's schedule a 20-minute technical call to walk through your AES topology and discuss edge cases like mid-call database failures before I commit to a delivery timeline.

You need AEP modules for intelligent call-routing, IVR prompt control/dynamic menus and reporting, plus refactors of legacy Java and C# CTI services and ES6 widgets that plug into agent desktops — all integrated via REST/JSON, databases and analytics. In scope: AEP flows exported for import, versioned CTI services with rollback, integration stubs, deployment guide and unit test results. Out of scope: CRM vendor changes or infra/network provisioning. Project fails if AES connectivity, call-state persistence across transfers, or rollback/versioning are not handled. Sharp insight: AEP flow variables do not reliably survive consult/transfers unless persisted to CallData or an external session store; that is the single highest risk for routing/IVR correctness in end-to-end tests. Relevant proof: Prior delivery experience on Avaya AES/AEP integrations plus refactors of Java CTI services and ES6 agent widgets (details available under NDA). Approach (high level): build modular AEP flows that call an external REST lookup for routing, refactor Java/C# services to explicit API contracts and versioned packages with rollback scripts, deliver ES6 widgets as modules calling the same REST layer, and run automated end-to-end tests against a lab AES instance. Proposed budget: $500, starting with a short discovery sprint to validate AES lab access. Do you already have a lab AES endpoint and CRM API (OpenAPI) to test against, or should a mock harness be provided?

I can help with this, I will build the new AEP call-routing modules, IVR flows (dynamic menus, prompt control, backend lookups), and reporting components. I will refactor the legacy Java and C# CTI services for stability, wire JavaScript widgets into agent desktops, and integrate with your REST/JSON, database, and CRM stack. For the IVR, I will structure flows as modular sub-applications in Orchestration Designer so each menu branch and lookup is independently testable — future routing changes will not require retesting the entire call tree. Questions: 1) Which AES version and connectivity (TSAPI, JTAPI, or Web Services) are current services using? 2) Lab AES environment ready, or should I factor setup into scope? Looking forward to your response.

I can help you. Integrating AEP with AES requires precise handling of UUI (User-to-User Information) data persistence to ensure CRM screen pops remain accurate during blind or warm transfers. I will focus on refactoring the legacy C# services to include robust recovery logic for TSAPI link drops, a common failure point in older CTI implementations. For the Orchestration Designer flows, I will implement strict session management to prevent resource leaks that often degrade AES performance over time. The JavaScript widgets will be built with a decoupled communication layer to handle potential CORS and TLS version mismatches between modern browsers and older AES Web Services.

This looks like a great fit, but I need some clarifications: Are your current Java services running on a specific version of Orchestration Designer (OD), and are there any existing middleware constraints for the TSAPI/JTAPI links? For the JavaScript widgets, do the web-based desktops utilize a specific framework (like Open CCX or a custom CRM iframe) that requires specific cross-origin or security handling? I will refactor your legacy C# and Java services to improve thread management and connection pooling to AES, ensuring higher stability for TSAPI streams. For new modules, I will develop modular AEP flows in Orchestration Designer, using a clean separation between call-control logic and backend REST/JSON lookups to facilitate easier reporting. I’ll also build the JavaScript desktop widgets using a lightweight, event-driven architecture to ensure real-time data synchronization between the IVR and the agent's view. To ensure a smooth hand-off, I will provide a unified intermediate structure for your data-capture logic, preventing "false positives" in reporting and making the code highly maintainable for your in-house team. Looking forward to discussing further. Best regards, Philip
