What this does

When someone dials your Aculab number, the engine starts a workflow on the AculabVoice channel. The standard StartTask, OutputTask, InputTask, EndTask, and SendToAgentTask are overridden for telephony — Output becomes AWS Polly text-to-speech, Input listens for speech and DTMF, End hangs up, SendToAgent transfers the call. The same diagram you draw for chat can answer phone calls.

The module wraps the Aculab Cloud REST API and adds voice-specific BPMN nodes for advanced input, DTMF capture, recording, sleep, call rejection, and live transcription with side-channel handler workflows.

What you can build

• IVR menus with AculabGetDigitsTask for keypad selection and SendToAgentTask for transfer to sales or support.
• Voice bots that combine AculabInputTask speech recognition with ChatGPT or ML modules for natural replies.
• Voicemail capture via AculabRecordTask, with a recording-available handler workflow that copies the file to blob storage.
• PIN-gated callbacks using AculabGetDigitsTask plus AculabRejectTask to hang up before answering on bad input.
• Live-transcribed compliance and sentiment analytics — AculabStartTranscriptionTask ships every recognised phrase to a separate handler workflow.
