Business landline telephony in the cloud

Help your customers reach the right department instantly with an IVR menu, call queues and routing rules. The big advantage of isaBEL: the PBX runs entirely in the cloud and is managed via a simple portal — no ISDN lines, no legacy PBX in your meter cabinet, and no maintenance engineer dropping by.

IVR menu

Professional menu that routes callers straight to the right department.

Call forwarding

Easily forward callers, including to a mobile colleague or external supplier.

Wallboard & dashboard

Real-time insight into wait times, call duration and service level for call centres.

Cloud-managed

No phone system on site — we operate the PBX 24/7 from our NL data centres.

What's included with isaBEL?

All the functionality of a professional phone system, without the hardware: • Unlimited calls to landline and mobile numbers across Europe • IVR menus, call queues and hunt groups • Call forwarding, voicemail-to-email and call recording • Opening hours, holiday schedules and public holiday routing • Wallboard and real-time statistics for call centres • Softphone on laptop and mobile — call from any location

Transparent pricing: €49.95 + €7 per extension

isaBEL uses a simple pricing model: a base bundle of €49.95 per month for the PBX, and €7 per month per extension or softphone. That covers everything: unlimited EU calls, all features and updates. No hidden costs, no per-minute charges within Europe, no invoice surprises. Calling internationally? Rates are visible upfront in your portal. Want to add or remove extensions? One click in the portal.

Keep your existing numbers

Your current landline numbers stay yours — we arrange the porting from your old provider. You remain reachable throughout the migration; we typically schedule the actual switch outside business hours so your team notices nothing on Monday morning. With 20 years of experience in business telephony, we know the common pitfalls: KPN number blocks, Vodafone fail-over paths, fax numbers that are still active. We tick them off one by one and test everything before go-live.

Combine with Microsoft Teams or mobile

isaBEL integrates seamlessly with Microsoft Teams and with Odido Business mobile subscriptions. One number that rings everywhere — on your desk phone, in Teams, on your mobile. One voicemail. One customer card in your CRM. Contact us at 085 013 4500 for a no-obligation consultation or request a quote directly.

Frequently asked questions

What does business landline telephony via isaBEL cost?

The base bundle is €49.95 per month for the PBX, plus €7 per month per extension or softphone. Unlimited EU calls are included, as is full functionality such as IVR, queues and call recording.

Can I keep my current business numbers?

Yes. We handle porting of your existing landline numbers from any Dutch provider free of charge. You stay reachable during the switch.

Do I still need a phone system on site?

No. isaBEL is a complete cloud PBX — nothing physical lives on your premises. Your SIP phones connect directly to our PBX in the data centre.

Can I keep my existing handsets?

If your handsets are SIP-compatible (most Polycom, Yealink, Snom and Gigaset phones) we simply reconfigure them. Otherwise we recommend suitable replacements — often from €80 per device.

Does isaBEL work with Microsoft Teams?

Yes. You can integrate isaBEL with Teams Phone so colleagues can call from Teams using the business number. One number that rings everywhere, one voicemail, one call history.

How quickly can I go live?

Configuration is usually complete within 1 working day. Number porting takes 1 to 3 weeks depending on your current provider — during that window we run a temporary number so you're never unreachable.
