LEONPBX

Telephony for real workflows.

We build telephony solutions around how your company works.

LEONPBX connects local PBX systems, endpoints and custom integrations into a solution that supports reception, branches, service teams and internal workflows. Sovereign operation, planned expansion and no unnecessary cloud dependency.

What you get

Telephony that makes work easier.

RUN

Less friction day to day

Calls land where they should. Ring groups, schedules, forwarding and queues are adapted to your real workflows.

CTRL

Control over operations and data

Calls, metadata, phonebooks and configuration stay in an environment you can control.

COST

Plannable investment

You avoid permanent license models and get a solution that can be expanded selectively when needed.

Digital sovereignty

Plan independently from US cloud providers.

Many cloud PBX systems move central communication data onto external platforms. LEONPBX is built differently: the PBX runs locally or in a controlled German or European environment.

Data control

Call data, recordings, phonebooks and configuration remain where you can control them.

Operational resilience

Internal telephony, extensions and key workflows remain predictable even when external cloud services fail or contract models change.

Compliance-friendly

Access, storage locations, backups and roles can be documented transparently and aligned with internal privacy requirements.

The goal: a modern telephony solution that reduces dependency on external platforms.

Your requirements

Which telephony task needs to be solved?

We plan telephony from the process outward: who calls, who needs to react, which systems should be involved and what should not create admin work in daily operations.

Reduce load on reception

Calls are routed by request, time, site or team so not every call has to be handled manually by reception.

Connect branches and sites

Multiple sites get a shared numbering and routing concept while still remaining locally usable.

Keep support and service reachable

Queues, callback paths, groups and escalations help prevent customers from getting lost in the system.

Connect CRM and business software

Click-to-call, caller recognition, phonebook sync and process data are integrated where your team works every day.

Roll out endpoints centrally

Phones, BLF keys, profiles and updates are provisioned predictably instead of maintaining every device manually.

Secure privacy-sensitive communication

Storage locations, roles, recordings, backups and access are planned for control and traceability.

LEONPBX modules

Solutions that go beyond a standard phone system

Our own extensions solve concrete challenges in reachability, collaboration and operations. They are centrally managed, delivered with signatures and enabled to match each customer environment.

Call continuity

Call protection during network loss

LEONPBX detects genuine media and reachability loss, keeps the active call alive and can reconnect the employee through their stored mobile number.

Fewer dropped calls during Wi-Fi or mobile network changes
Reachability

Intelligent number routing

Inbound call paths are built visually and simulated before activation. Time windows, caller rules, dynamic extensions and safe fallback targets remain traceable.

Complex routing without opaque individual rules
Presence & collaboration

Teams states, BLF and pickup connected

Custom Microsoft Teams states are translated into telephony. Available, busy, on a call or unavailable are instantly visible through clear BLF colors; authorized employees pick up ringing calls directly.

Faster coordination and fewer missed calls
Operations & security

Updates, network and system health under control

Signed extensions, protected voice connections, hardware health, storage, live logs and core telephony processes are monitored together and updated in a controlled process.

Predictable operations with traceable changes
Workplaces

Centrally deploy phones and softphones

Extensions, desk phones, function keys and softphone profiles originate from one central configuration. Caller number and name are displayed clearly, while the customer portal and branded interface remain consistent across workplaces.

New employees and devices become productive sooner
Data & integration

Call data and contacts where teams need them

Second-level call analytics, scheduled CSV reports and synchronized CRM, CSV, JSON or database contacts connect telephony with daily business processes.

Better reporting without manual data silos

LEONPBX softphone

The phone system employees can take with them

LEONPBX brings complete business telephony to Windows, iOS and Android: centrally configured, intuitive to use and closely connected with contacts, presence, queues, call forwarding and business workflows.

Ready without manual setup Accounts, server paths and approved functions are delivered centrally by the PBX.

Integrated into workflows Click-to-call, desk phone control, queues and actions work together directly.

Call Revive protects active calls

After a connection loss, LEONPBX keeps the active call and reconnects the employee in a controlled way through the stored mobile number.

Centrally configured

Extensions, server paths, contacts and approved functions are delivered automatically by the phone system.

Team status, BLF and pickup

Clear colors show availability and call status. Authorized colleagues can pick up ringing calls directly from the team view.

Recognize name and number instantly

LEONPBX presents caller identity clearly and connects it with centrally maintained company and CRM contacts.

Click-to-call and desk phone control

Phone links from browsers, CRM systems and business applications start calls through the softphone or desk phone.

Securely reachable everywhere

SIP-TLS, SRTP, HTTPS provisioning, mobile push notifications and the LEONPBX gateway provide reliable reachability away from the office.

Windows, iOS and Android use the same centrally managed telephony – with encrypted connections, mobile push calls and consistent business functions.

One operating concept for the office, home and mobile work

Real LEONPBX interfaces on every device. The views change automatically to show how calls, team presence and system functions work together day to day.

Tailored solutions for our customers

Three examples of how PBX, endpoints, web portals and internal systems are connected into practical day-to-day solutions.

01

Customer web portal for PBX self-service

For one customer, a web portal was built that allowed employees to control selected telephony functions themselves. Permissions, PBX configuration, endpoints and internal workflows were interconnected so changes were controlled, traceable and usable without an admin ticket.

  • Self-service instead of support queues
  • Role and permission model for sensitive functions
  • Direct connection to PBX, phonebook and internal workflows
02

PBX and Yealink provisioning

Custom PBX extensions connect Yealink provisioning directly to extensions: model profiles, BLF keys, language, time, wallpaper and automatic check-sync actions after saving.

  • Automatically generated device configuration
  • Practical planning for Yealink, Snom and other endpoints
03

LEONPBX softphone & click-to-call

Our softphone was extended with custom deskphone click-to-call routes. Phone links from browsers, CRM systems or business applications can run through either the softphone or desk phone.

  • API bridge for desk phones
  • Fallback logic when PBX integration is unavailable
