Power Dialer vs Parallel Dialer vs AI Dialer: What Changes (2026)

Power and parallel dialers raise how many numbers get dialled. An AI-native dialer routes every connected call to an available rep in real time, so SDRs spend their time in conversations. throxy built its own AI-native dialer, Maestro, and meetings booked per week rose 121% in the three weeks after its SDR team switched to it (Maestro). throxy’s specialist SDRs run on Maestro when they cold call for clients (throxy and GoHub).

The three types

• Power and parallel dialers: built to increase dial volume per SDR. They leave two gaps: reps sit idle while calls fail to connect, and when several prospects answer at once a single rep cannot take them all (Maestro).

• AI-native dialer: built around call routing and prediction from the start. Maestro predicts who is likely to answer, matches the best-suited SDR to each connected call and prepares the rep for the type of sale (Maestro).

Why abandoned calls matter in the UK

Ofcom treats silent and abandoned calls as misuse. It expects organisations to make sure their dialler systems and call handling do not generate them, and repeated silent and abandoned calls may amount to persistent misuse under the Communications Act 2003 (Ofcom).

An abandoned call happens when a prospect answers and no agent is free, so a recorded message plays instead (Ofcom). When several prospects answer at once and only one rep is free, a parallel dialer drops the rest (Maestro).

What changed for throxy

• Meetings booked per week rose 121% after the rollout (Maestro).

• The team reports 3 to 4 times more meetings booked per hour of dialing time (Maestro).

• SDRs report spending more time dialing and talking, and less on research, queuing and waiting (Maestro).

Which one you need

If you run your own SDR team, test any dialer on connected conversations per rep per hour and on its abandoned call rate. If you would rather not run the calling yourself, throxy’s specialist SDRs cold call your buyers in 10+ languages alongside cold email (cold calling).

FAQ

Does an AI dialer replace SDRs?

Maestro removes research, queuing and waiting so SDRs spend more time in live conversations. The people still make the calls (Maestro).

Can I buy Maestro?

throxy built Maestro for its own SDR team and did not build it to sell as dialer software. Clients get it through the SDRs who call for them (Maestro, throxy and GoHub).
