A call-sidecar is not a replacement for voice. It is a precision layer that appears during a live call so agents and callers can type the details that are easiest to mishear out loud.
When someone needs to share a long email address, policy number, street address, or compliance acknowledgement, the caller can type it in-session while the conversation stays on the phone line. The agent keeps rapport and context in voice; the sidecar captures exact characters in text.
What it does in practice
- Runs alongside an active call, not before or after it.
- Captures high-risk details in typed form at the exact moment they matter.
- Supports compliance flow by presenting precise language in-session.
- Ends with the call so there is no long-lived chat thread to manage.
Why this matters operationally
Voice is excellent for empathy, context, and decision-making. It is weaker for exact string capture under pressure. A sidecar closes that structural gap by giving teams a real-time fallback for precision without forcing a channel switch.
That means fewer repeated spell-outs, fewer callback loops from wrong details, and less friction in QA and compliance checks.
