You protect your investment
Equipment that still works well stays in use. You replace only what really needs replacing.
Move to IP telephony and keep what already works
We connect new IP and SIP technologies to your existing call server, phones and lines. The move happens gradually, without downtime and without throwing away equipment that still does its job.
From traditional telephony to IP, step by step
Traditional phone lines and old call servers are being phased out, and new services run over the internet. A hybrid solution lets you move at your own pace: old and new work together as one system.
What you have today
Existing system
- Existing call server (PBX)
- Analogue or digital phones
- Traditional (ISDN and analogue) lines
What TRS adds
New part of the system
- An IP call server or an extension of the existing one
- A VoIP gateway that connects old and new
- Connection to the operator's SIP trunk
Result
One system
- One system, one management
- Old and new phones work together
- Ready for further growth
Why a hybrid solution?
A gradual move
Site by site, department by department, without a big-bang switch and its risks.
No downtime
We plan the move so the phones keep working throughout, for employees and clients alike.
One management
You see and configure the old and new parts of the system from one place.
Do you recognise your situation?
The most common cases clients come to us with.
Scenario 1
The operator is switching off traditional lines
We connect your call server to the operator's SIP trunk, so you keep working as before, with the same numbers.
Scenario 2
A hotel with analogue room phones
The room phones and cabling stay, while reception and the offices get modern IP features.
Scenario 3
Several sites, different equipment
We connect call servers at different sites into one network, so internal calls between them work as if you were in the same building.
Scenario 4
The call server is old but still works
We add an IP part next to it and move users over gradually, until the old equipment can be safely switched off.

Questions and answers
Key terms, simply explained
Telephony is full of abbreviations. Here is what they mean, without the jargon.
What is hybrid telephony?
It is a system in which old and new telephony work together. For example, the existing call server and analogue phones keep working, and we add IP phones and internet lines alongside them. To the user, everything looks like one system.
What is IP telephony (VoIP)?
VoIP (Voice over IP) means voice travels over the computer network and the internet, just like e-mail or video, instead of over traditional phone wires. The phone then plugs into the same network as the computer.
What is SIP?
SIP is the “language” IP phones, call servers and operators use to set up, redirect and end a call. Thanks to this common standard, equipment from different manufacturers can work together.
What is a SIP trunk?
A SIP trunk is a phone line over the internet provided by a telecom operator. Instead of several physical lines entering the building, one internet connection carries many simultaneous calls and your numbers. We connect and configure the SIP trunk with your call server.
What is a call server (PBX / IP-PBX)?
The call server is the “brain” of a company phone system: it assigns extensions, routes calls, handles voicemail and internal calls. A PBX is a traditional call server, and an IP-PBX is a modern one that runs over the computer network.
What is a VoIP gateway?
A gateway is a “translator” between the old and new worlds. It connects analogue phones, fax machines or old lines to the IP system, so older equipment can stay in use.
Do we have to replace all phones and the call server?
No. That is exactly the point of a hybrid solution: we keep equipment that still works well and replace only what is necessary. At the start we assess together what stays and what is due for replacement.
Do we keep our existing phone numbers?
In most cases, yes. Numbers are assigned by the operator, and moving them to a SIP trunk is arranged with them. We coordinate the whole process so clients keep calling the same numbers.
Will the move disrupt our business?
We plan the move in phases and at times that suit you, and the old system keeps running until the new part has been verified. The goal is for employees and clients not to notice the change, except for the new features.
