Aircall's Power Dialer calls your list one number at a time, and its "parallel calling" means putting someone on hold to call another. Sonik dials several prospects at once, skips voicemails and no-answers, and connects the rep the instant a human picks up. Customers measured up to 10 conversations per hour.

Aircall's AI summarises previous interactions and CRM data, which is useful once a relationship exists. On a cold call there is no history yet. Sonik researches every prospect before the dial: past experiences, job offers, annual reports and latest communications, so reps open with context instead of a script.

Aircall lets a rep drop a pre-recorded voicemail during a call. Sonik runs voicemail campaigns at scale to turn cold lists into inbound calls, and when a prospect mentions a colleague, finds that person, their number and creates them in your CRM, doubling conversion on referrals.

Sonik feeds your pipeline with website visitors, contacts recommended during cold calls, people interacting with competitors, companies hiring for the need you solve and wrong-number replacements. Every team gets a dedicated cold-call training session with a human expert, individual ratings, and industry insights analysed by a CSM. Aircall offers AI coaching and analytics; the human, outbound-specific layer is what Sonik adds.
