VoIP & Internet Telephony

What is Voice over IP (VoIP)?

With Voice over IP, voice information is transmitted in a digital format over the internet. VoIP thus replaces classic analogue and ISDN telephony over public telephone lines (PSTN) and conventional telephone exchanges (PBX). Several phone calls can be made simultaneously over a single broadband line – without the need for a separate telephone infrastructure. Incoming calls to your extension are automatically forwarded to whichever device you are currently working on: desk phone in the office, softphone in the home office, smartphone in the field. Your office number is no longer tied to the desk phone but follows you wherever you go.

What advantages does VoIP offer your company?

With VoIP phones, you and your employees communicate worldwide under a single phone system – regardless of geographical location. When you switch to VoIP and internet telephony, your phone charges drop noticeably, since calls within the system are free and external connections over the internet become significantly cheaper. On top of this, features such as voicemail-to-email, call forwarding, conferencing and call statistics are integrated as standard.

VoIP in emergency situations and disaster recovery

Does your company rely on continuous voice communication? Then a cloud VoIP system makes particularly good sense. If traditional systems suffer a hardware failure, in an emergency you can only fall back on mobile phones or a second site. Restoring classic telephone systems (PBX) after a disaster is, in our experience, very difficult, lengthy and expensive. If you use cloud VoIP instead, you need no dedicated hardware or software in your data centre for disaster recovery. Your employees continue to communicate without restriction – via internet telephony in the home office or over a second local broadband line at an alternative site.

Phase 1: analysis of your current telephony

We start with a detailed inventory: which system is currently in use, how many extensions are needed, which phone numbers have to be ported, how is the internet connection dimensioned? We analyse your existing infrastructure and check whether your internet connection provides sufficient bandwidth and Quality of Service (QoS) for smooth VoIP telephony.

Phase 2: conception and selection of the right solution

Based on the analysis, we develop a tailored concept. Should telephony be deeply integrated into Microsoft Teams, should a classic cloud phone system be used, or a hybrid solution with local connectivity? We advise you on a vendor-independent basis and take into account your individual requirements for functionality, security and scalability.

Phase 3: migration and number porting

We plan the actual move so that your business operations are not affected. Existing phone numbers are ported in full and new devices are delivered pre-configured. The changeover takes place in the background – on the cut-over date you are reachable under the same numbers as before, but now via the modern cloud infrastructure.

Phase 4: training and rollout

So that your employees can take advantage of all the benefits of the new telephony, we give your team targeted training. We show how calls are forwarded, conferences are set up and voicemails are managed – on the desk phone, in the softphone and in Microsoft Teams.

Phase 5: operation, support and ongoing development

After commissioning, we remain your dedicated point of contact. We monitor voice quality, take care of updates and flexibly adapt the system when new employees, sites or features are added. This keeps your telephony permanently powerful, secure and predictable.
