IP telephony

We deliver IP telephony for companies that want to be mobile and efficient. An IP phone works and looks like an ordinary office phone. The only difference is that the IP phone is not plugged into a phone jack, but is instead connected to the internet. The conversation therefore goes via the Internet instead of the traditional telephone lines.

What is IP telephony?

What is IP telephony?

IP telephony stands for Internet Protocol telephony. Thus, it is a service for telephony via the Internet instead of the traditional PSTN. IP telephony uses “internet protocols” to communicate digitally via the internet. So it is your phone via a high-speed Internet line instead of being a fixed phone. Instead of using the traditional telephone system, companies calling via IP telephony can utilize an internet connection and the included hardware and applications to communicate more effectively. More companies choose to use the technology to improve the organization’s productivity while reducing operating costs. With IP telephony you get a functional and flexible company telephony at a fraction of the cost of a traditional fixed exchange solution.

IP telephony combines the mobility of a mobile phone with the main advantage of a landline telephone, namely stability. VoIP services can be used with any high-speed internet connection (DSL, cable or other types), regardless of location or vendor.

Is IP telephony and VoIP the same thing?

Is IP telephony and VoIP the same thing?

It is easy to mix the terms VoIP and IP telephony or think that there are different words for the same thing. But, is it really so? No, VoIP and IP telephony are not the same. In simple terms, VoIP is a part of IP telephony. IP stands for Internet Protocol and VoIP stands for Voice over Internet Protocol. IP telephony refers to the digital side of telecommunications, voice communication is then made via VoIP. Your voice is thus passed over the internet and the protocol defines how your voice will then move over a network. One can think of IP telephony as an overall concept and VoIP is in turn a digital means of transport for bringing the telephone call. An IP telephony system can be, for example, an IP PBX that has VoIP. The difference is quite subtle and it is not surprising that it is sometimes mixed together.

What are the benefits of IP telephony?

Telephony as a service

There are many benefits of IP telephony. Unlike a fixed telephone exchange, IP telephony is mainly SaaS implementations. This enables you to integrate your telephony system with other powerful business applications such as customer databases and CRM systems. With IP telephony, employees and customers get better opportunities to interact with each other in an efficient manner. Something that leads to better business results and more satisfied customers.


If you want a mobile workforce then IP telephony is really something that you should consider. You can take an IP phone with you abroad or to the summer cottage and connect to the internet so it works as usual. This also helps if staff need to be mobile at the office itself, because the phones are easy to move around.

Make the most of the internet

A common question that companies ask themselves when they are considering implementing IP telephony is how big the impact it will have on Internet usage, which is not so strange. According to a study by the University of West, 35-50% of phone calls were spent in silence. Something that may have used up valuable data. But IP telephony uses VAD (voice activation detection) which compresses silent data as much as possible. In silence, your IP system searches for total bandwidth allocation, making voice-to-voice calls an effective use of data.

Transmission of multi media

IP telephony provides more than just voice services. These systems can also handle conference calls and video calls where both picture and sound need to be transferred simultaneously. Ordinary old business switches cannot provide businesses with what is needed to be a modern company today. An extensive IP phone system eliminates software and hardware overrun by consolidating all of these conference needs into one solution.

Lower costs

Installation and maintenance of an IP system can be done through in-house network engineers, or through a business partner, if you do not want to be responsible for hiring and managing this. IP systems also do not require proprietary hardware or function updates. With SIP (session initiation protocol) trunking you only pay for the data you use. And it is through SIP trunking that you get audio, video and private teleconferencing without having to pay for extra channels.

Frequently asked questions about IP telephony

What is the difference between IP telephony and common analogue telephony?

There are two fundamental differences between common analogue telephony and IP telephony. Traditional analogue telephony uses equipment dedicated to analogue telephony. With IP telephony the public internet is used to make the call. With analogue telephony, a specific capacity is also reserved for a particular call and with IP telephony the capacity that is available is used.

Is it free to call with IP telephony?

No, it is not free to call with IP telephony. You still have to pay for outgoing traffic that goes out in the public telecommunications network because an operator is the carrier of the traffic.

Is it safe to call with IP telephony?

With IP telephony, you can encrypt the conversation, something you do not do via a regular analog phone. Therefore, IP telephony is considered a safer source to call via.

How is the sound quality when calling through IP telephony?

Provided you have a good connection, the quality is significantly better when you call via IP telephony. The frequency range in the analogue network is more limited, while IP telephony has a larger frequency range. So if you have good technology that can pick up this range, you get a lot better sound quality in your conversation. If you lose connection while calling with IP telephony, the sound tends to get more boxy. While if the same thing happens with analogue telephony, this will make the sound only weaker.

Can you use IP telephony via a mobile phone?

Yes, you can use IP telephony via your mobile phone, then it is called  Mobile VoIP. Mobile VoIP is advantageously used with WI-FI in your mobile phone. This is because you will need as good connection as possible so that the quality of your call is not affected. The technology is based on the same idea as regular IP telephony, namely that the conversation goes over the internet.
