Template Wizards

Launch proven call flows in three steps. Select a template, plug in your contacts and press start.

Visual Designer

Drag-and-drop editor for conditional logic, branching, retries, human versus machine routing and timed delays.

Text-to-Speech

Generate audio on the fly via Google Cloud TTS with variable content per call, or upload pre-recorded WAV files.

DTMF Collection

Capture keypad responses mid-call and branch the conversation, transfer to a live agent or end the call accordingly.

Live Transfer

Route qualified callers to a specific agent queue, extension or external phone number with context already collected.

Campaign Testing
