Koncert Agent-Assisted Dialer pairs a sales representative with a human dialing assistant who places and screens calls.
Koncert Agent-Assisted Dialer is the human-assisted dialing option in Koncert's sales engagement platform. A trained dialing assistant works the representative's calling list, places the calls, and stays on the line to navigate phone trees and screen out voicemail and non-decision-makers, handing each qualified conversation to the representative who takes over the live discussion.
The product suits teams that want the throughput of automated dialing without giving up a human on the front end of each call, and it sits alongside the automated AI Power Dialer and multi-line AI Parallel Dialer in the same platform. It uses the platform's CRM synchronization so call outcomes, dispositions, and recordings flow back to the connected sales system.
