Cloud dialler vs on-premise dialler
A cloud dialler is run by the provider. An on-premise dialler runs on servers the contact centre operates. 626Dialler is hosted by Alveus for every customer. The right-hand column is the on-premise model in general, not a second 626Dialler product.

This comparison describes two operating models in general terms. It is not a review of any named product, it is not legal advice, and it does not promise any outcome. 626Dialler details are taken from our pricing and product pages as at the date shown.
| Topic | Hosted, including 626Dialler | On-premise model |
|---|---|---|
| Who runs the platform | Alveus hosts 626Dialler for every customer and applies the platform updates. | Your organisation, or a contractor you keep, operates the servers, the patches and the failover. |
| Where recordings sit | On the hosted platform. Who can play them, and how long you keep them, is part of your own retention setup. PCI payment processing is available, and recordings can use PCI pause. | On infrastructure you operate. Retention and access are still yours to define. |
| Telephony | Twilio is available on Growth and Enterprise. You can connect your own SIP trunk. | Usually the trunks you order and maintain. The number you present is still your choice. |
| Seats | Seat-based pricing. Starter is up to 10 agent seats, Growth up to 50, Enterprise is unlimited. See the pricing page for what each plan includes. | Capacity depends on the servers and trunks you run, and on the contract for that software. |
| Dial modes | Predictive on Starter, Growth and Enterprise. Progressive and preview on Growth and Enterprise. Manual as well. | Whatever modes that system actually has. This page does not describe another product's modes. |
| Abandoned-call target | You set the target. Pacing eases off as the live rate approaches it. You can report on it per campaign, per day. | You would set the equivalent control in that system, where it has one. Ofcom's statement names no abandoned-call threshold either way. |
| CRM and API | 626CRM, our own hosted CRM, is included on Growth and Enterprise. Salesforce, HubSpot, Microsoft Dynamics and Zendesk are integrations with a CRM you already use, with call activity written back after each call. A documented REST API is available. | Depends on what you connect. A hosted connector is not the same thing as the CRM itself. |
| Transcription | AI transcription and sentiment are on Enterprise. | Depends on the system you run. This page does not claim an on-premise product lacks it. |
| Support | Every plan includes 24/7 email and WhatsApp support. Growth adds priority handling. Enterprise adds a named account manager. | Whoever you employ or contract to keep the platform running. |
The decision is who operates the platform
Both models place outbound calls. The split is who patches the software, who adds capacity, and who you call when a campaign will not dial. On 626Dialler that operator is Alveus, for every customer. On an on-premise system it is your team. Calling rules do not follow the server. Silent calls, abandoned calls, CLI and the TPS are about the person who answers.
Ofcom's persistent-misuse statement of 20 December 2016, in force since 1 March 2017, names no abandoned-call threshold. You set the target on 626Dialler either way you deploy a dialler, and pacing eases off as the rate approaches the target you chose. Read the persistent misuse guide for the formula, and the longer note cloud dialler vs on-premise.
What stays on your side of the line
You still choose the dial mode, the CLI, the list, the information message and the do-not-call entries. TPS and CTPS suppression is on every 626Dialler plan. Predictive dialling is on every plan. Progressive and preview need Growth or Enterprise. Answerphone detection can be tuned per campaign. None of that is decided by the fact the platform is hosted.
If the question is whether to assemble the dialler yourselves, that is a different comparison: hosted dialler versus a DIY build. Plan limits are on the pricing page. Book a demo to see the hosted campaign settings.
