AI surfaces recommendations on where agents fail and what prompt changes will lift performance.

In-call workflow
Phone Calls Have Complex Moving Parts. Persistence Handles Them All Natively No Custom Code Required.
Agents navigate external phone trees, press the right keys, and wait on hold so your team never has to.

While waiting or during gaps, agents keep the conversation natural so callers stay engaged.

Detect voicemail vs. live pickup and leave a natural message or reroute based on your rules.

Specialist agents hand off to each other mid-call so complex requests resolve without a human touch.

Call external APIs, look up orders, and take real actions inside a live conversation.

Define exactly how and when calls end successfully transfer, complete, escalate, or retry.

Outbound
Don't Just Wait For Calls. Persistence Agents Proactively Reach Customers At Scale.
Upload a contact list or trigger via API and run thousands of concurrent outbound calls appointment reminders, lead qualification, surveys, and collections. Schedule for the perfect moment, respect time zones and dial windows.
