A hosted dialer is dialing software that runs on the provider's servers and that your team uses through a browser or an app. There is no server room, no PBX to maintain and no IT ticket to add a rep. It is also called a cloud dialer.
One thing is easy to miss: "hosted" describes where the software runs, not how it dials. A hosted dialer can be a power, parallel or predictive dialer. For a European B2B outbound team, the real work is in five checks: CRM sync, numbers, audio latency, data location and reliability.
The two models differ on a short list of points:
The trade-off is dependence: if the provider has an outage, you wait for them. That is why reliability is one of the five checks below, and not a footnote.
For a team of 5 to 100 reps doing outbound, hosted is the default. On-premise still has a case for large, stable contact centers with strict internal data rules and existing telephony they cannot replace. We cover the same shift in VoIP vs classic telephony for prospecting.
In our experience, a hosted dialer goes from contract to first calls in days, not quarters. The steps are the same everywhere:
Budget the cost on both sides. A hosted dialer usually charges per seat per month, plus number rental and per-minute charges by destination. Ask for the per-minute rates for every country you call, because mobile minutes in some European markets cost noticeably more than domestic ones. The total per rep, per month, at your real call volume is the only number to compare.
The slow part is almost never the software. It is clean phone data and a decision on which numbers to show.
Ask whether it is two-way, how fast outcomes appear on the record, and which field the dialer dials when a contact has several numbers. A dialer that does not write back is a second system your reps will stop updating. See what changes when you connect your dialer to your CRM.
Ask which number types you can use in each country, how the provider monitors number reputation, and what happens when a number is labelled as spam. Rules and carrier practices differ by country, so ask for written answers for every market you call. Our guide on why numbers show as spam lists the fixes.
Voice calls need low delay in both directions. A common reference point is the ITU recommendation of under 150 milliseconds one-way for most conversational use. The number matters less than where the media servers are: a rep in Lyon on servers in another region can sound slightly off, and a prospect who hears a delay hangs up. Test from your reps' own connections, at your own calling hours.
Ask where call recordings, transcripts and contact data are stored and processed, which sub-processors the provider uses, and what transfer mechanism applies if any data leaves the EEA. Ask for the data processing agreement before the pilot, not after. Recording rules are covered in recording sales calls under GDPR and the CNIL.
A hosted dialer is only as good as its uptime. Ask for the SLA, the public status history and what happens to a live session when a rep's connection drops. A calling block lost to an outage at 4pm, the slot with the best connect rate in our benchmark at 15.8%, costs real pipeline.
Moving to the cloud does not change your connect rate. In our 1,000,000-call benchmark in France, the average is 11.3%, and it depends on list quality, persona, time slot and number reputation. A hosted power dialer used like a desk phone gives you desk-phone results.
The dialing mode decides how many conversations a rep gets from those dials. See our map of auto dialer types and the rules in France before you pick one.
Sonik is a cloud dialer built for outbound teams in France and Europe. It connects to your CRM, uses the signals already in it to decide who to call first, and runs parallel dialing to give reps 5x more conversations.

Our advice on any hosted dialer, ours included: run a one-week pilot with two reps on your own list, then measure connect rate, time to connect and audio quality from their actual setups. Brochure numbers do not survive contact with your data. Current plans are on the pricing page.
A hosted dialer is the right default for B2B outbound: faster to start, simpler to scale, easier to run remotely. Judge it on CRM sync, numbers, latency, data location and uptime, not on the feature list. This week, write those five questions down and send them to the two vendors on your shortlist.
