How is it different from the cloud?

The system runs on your own infrastructure: data stays on site, the investment is one-time, and local calls keep working even during an internet outage.

What hardware do I need?

A virtualization environment (VMware, Proxmox) or a dedicated server. We determine the exact sizing during the survey.

How long does deployment take?

The time from survey to go-live depends on the size of the system — we carry out the migration with zero downtime.

Is remote support available?

Yes, under a support contract we provide remote monitoring and troubleshooting as well.

Can it be extended with the cloud later?

Yes. In the hybrid model, cloud backup and overflow can be added to the local system — a gradual transition is also possible.

Full control on your own infrastructure — powered by Asterisk

We deploy, configure and operate your enterprise PBX alongside your own servers — with a hybrid cloud expansion option and no vendor lock-in.

Why an on-premises PBX?

Data sovereignty and compliance — All call data, recordings and logs stay within your own servers and never leave to a third-party cloud. Ideal for GDPR-sensitive sectors: finance, healthcare, public services.
One-off investment, low TCO — No per-seat monthly licence fee. The hardware and installation investment typically pays back within 2–3 years compared to SaaS pricing, especially for organisations with 30+ extensions.
Deep integration with business systems — Via Asterisk AGI/AMI/ARI interfaces the PBX connects to your CRM, ERP, helpdesk or any custom business system — we handle the integration wiring.
Internet-outage resilience — An on-premises deployment keeps internal calls running without internet. For critical infrastructure — hospitals, utilities, production lines — this is a baseline requirement.
Hybrid option: on-prem + cloud overflow — Your on-premises PBX and Innotel Cloud PBX can be bridged: the cloud side handles expansion, disaster backup and home office, while sensitive traffic stays local.
Integration of existing analogue and ISDN equipment — Analogue extensions, fax machines, door openers: the Asterisk-based setup retains your existing equipment via FXS/FXO cards while opening to the future on SIP channels.

How it works

1Discovery and design — We map your existing infrastructure, extension count, call-flow requirements and growth plan, then deliver a concrete technical proposal and project schedule.
2Installation and configuration — We deliver and install the hardware, configure the Asterisk-based software, call logic, IVR, recording and integrations.
3Zero-downtime migration — We migrate your existing numbers and extensions in parallel operation; the cutover happens outside business hours with no perceptible disruption.
4Ongoing operations and support — Under a managed service contract we handle updates, monitoring and incident resolution — from remote support to on-site intervention.
