VoIP and modern business telephony

Telephony only gets noticed when a call fails to arrive. We switch you over without losing numbers — and settle beforehand who is reachable, when and where.

// Starting point

The system in the basement has lasted a long time

In many companies the phone system has stood in the plant room since the last refit and does its job. It becomes uncomfortable when a card fails and the supplier from back then no longer stocks the part — or when nobody remembers how to change a call diversion.

The second trigger is how people work. A system that ties extensions firmly to handsets on desks fits badly with teams who work from home two days a week or move between sites.

So a switch is rarely a purely technical matter. It is the right moment to rethink call distribution: who picks up when nobody in sales answers, what happens after closing time, and who actually listens to the voicemail.

How numbers move without getting lost

Porting is the part with fixed dates. Everything else arranges itself around it.

01 · Inventory

Record numbers and routes

Which numbers belong to the company, which extensions are assigned, which special numbers and attachments hang off the old system.

02 · Preparation

Get network and devices ready

Check cabling, configure network equipment for voice, provide handsets and build the new call distribution — all before the porting date.

03 · Porting

Switch on the agreed day

The numbers move on the agreed date. We are available that day and test every number with a live call, inbound and outbound.

04 · Follow-up

Fine tuning in daily use

Over the first weeks we adjust call groups, announcements and cover arrangements wherever practice differs from the plan.

// Reachability

What this lets you govern

The real gain is not in the technology. It is that calls reliably land with somebody.

Points that have to be settled first

They sound unremarkable, but they are the most common reasons for trouble on the day.

  • Power cuts and reachability

    Without power in the building no IP phone works. For emergencies we settle in advance which mobile route applies.

  • Emergency address per connection

    The location is registered deliberately and updated when people move. It does not follow on its own.

  • Special attachments in the building

    Door intercoms, lift emergency calls, alarm systems or time recording often hang unnoticed off the old system.

  • Who maintains it afterwards?

    Changing call groups and announcements should be possible without an engineer. We agree who may do it and show them how.

  • Protection against toll fraud

    Phone connections are attacked deliberately. We restrict destination ranges and hours and watch for unusual behavior.

What gets asked most often before a switch

Your case is unusual? Get in touch
01

Can we keep our phone numbers?

As a rule, yes. Existing numbers can move to the new connection, usually including the whole extension block. We prepare the port, agree the date and keep the old connection live until the switch.

02

A system on site or a hosted connection?

A system in your own building pays off where many special cases have to be covered, or where door intercoms, alarm dialling and machinery are attached. A hosted connection saves maintenance and suits distributed sites. We recommend based on how you are set up, not on what is fashionable.

03

What do we need to watch for with emergency calls?

With internet-based telephony the location is not automatically correct, because a handset can stand anywhere. We register the address for each connection and point out that during a power cut in the building no phone will work — unlike some of the older kit.

04

What happens to our fax machine?

Fax machines get along poorly with voice carried over the network. The usual route is a service that drops incoming faxes into a mailbox as a file. Where a physical machine has to stay, we check beforehand whether the line will carry it.

05

Do we need new handsets?

Not necessarily. Newer desk phones can often be reused, older ones cannot. Many companies get by with a mix of a few desk phones, headsets and software on the computer — we decide that workplace by workplace.

06

How does the switch affect our network?

Voice reacts badly to fluctuation. So we check cabling, network equipment and the line beforehand and configure the network to give calls priority. Skip that step and any telephony becomes unreliable.
