Power and parallel dialer with live AI coaching inside your CRM
Dial one contact at a time or call up to five lines simultaneously and be connected to whoever answers, directly from supported CRMs and sales platforms.
Eligible contacts are ranked by estimated likelihood of answering so reps spend each call block on the numbers most likely to turn into a conversation.
Suggested replies to questions and objections appear during the live call, with a transcript and notes available for review afterward.
Managers and teammates share a calling room where they can see who is dialing, listen to live conversations and coach reps as they happen.
