Live Call Simulation
+1 (415) 890-CALN • Active WebRTC Stream
Engineered for High Reliability
Agents with guardrails: they only offer times from your calendar and stick to your instructions.
Inbound Call Reception
Assign a dedicated phone number. The agent greets callers with human-like prosody, understands nuanced requests, and answers common questions from your knowledge base.
Real-Time Calendar Sync
Checks your connected Google or Outlook calendars for open times before offering a slot, so it doesn't double-book you.
WhatsApp & SMS Summaries
Sends the caller a calendar invite and confirmation by email, plus a WhatsApp summary when you connect Sendish.
Natural, Interruptible Conversation
Engineered on modern WebRTC streaming architectures so conversations feel natural, responsive, and completely fluid.
