Phone systems

Mitel communications for businesses

From five extensions to several thousand users across many sites: I design, build and document your communication system – with network and security in mind from day one.

Services

MiVoice Business

The core platform for businesses: virtual or on hardware (e.g. SMB controller, EX controller), standalone or clustered across sites.

MiCollab & mobile working

Softphone, presence, chat, voicemail and conferencing on PC and mobile – including integration with Microsoft Teams.

MiVoice Border Gateway

Secure connection of home offices, branch offices and SIP trunks via the DMZ – clustered for redundancy if required.

Network & firewall

VLANs, QoS, ports and firewall rules matched to the system. Your IT provider receives a ready-made firewall matrix.

Migration

Replacing older systems (including Siemens/Hicom and other vendors) during live operation. Existing two-wire cabling can often be reused.

Devices & DECT

Desk and conference phones, DECT and IP-DECT with site surveys, analogue gateways for fax, door intercoms and legacy devices.

How a project works

  1. Analysis & design

    Existing setup, requirements, network and firewall – recorded in a requirements and functional specification.

  2. Preparation

    Network changes, coordination with carrier and IT, pre-configuration of the system.

  3. Installation

    Set-up, configuration and integration into your IT – usually within a few days, depending on scope.

  4. Testing & acceptance

    Joint testing, acceptance report and handover of the complete documentation.

  5. Operation

    Ongoing support under a maintenance contract – remotely or on site.

Documentation as a service

A system is only as good as its documentation. Every project includes:

  • System documentation covering all components and networks
  • Functional specification and acceptance report
  • Cross-connect plan
  • Firewall matrix for the IT department
  • Credentials handed over separately and encrypted

For Mitel partners I also produce these documents as a service – with your logo and in German, English, French, Spanish and other languages.

Training

For six years I have been training Mitel partners and engineers, among others for ComBridge AG in Switzerland. Topics include:

  • Commissioning MiVoice Business (SMB and EX controller, virtual)
  • MiCollab and MiVoice Border Gateway
  • Analogue gateways and terminal adapters
  • Administration for your IT staff

On site or online, in German or English.

Frequently asked questions

When is a new phone system worth it?

When vendor support ends, spare parts become scarce, maintenance gets expensive, or you need mobile working, home office and Teams integration. I review your setup and tell you honestly whether an upgrade is enough.

Can I keep my existing phones and cabling?

Often, yes. Analogue phones, fax machines and door intercoms can be connected via analogue gateways; the two-wire cabling stays.

Do you support systems you did not install?

Yes. After an initial review I also take over maintenance of Mitel systems installed by others.

Do you work outside Germany?

Yes. I have delivered projects in many countries. Much is done remotely; for installation and acceptance I come on site.

Which company sizes do you serve?

I add the most value for organisations with around 50 or more employees, several sites or special requirements such as hotels. Smaller systems are welcome when the fit is right.
