VoIP phones – what are they, and why are they worth it?


An IP phone is a device that differs from the traditional one mainly in that it is not connected to the telephone network. The range is received via a computer network, and the telephone infrastructure is managed by VoIP telephony. The abbreviation is called Voice over Internet Protocol, which is simply a technology of voice transmission over the Internet.

VoIP, although it was created for data transmission after some time, gained a world standard as a voice transmission network. And that has also become the core functionality of VoIP. The connection is made bypassing traditional terrestrial transmitters, using Internet links based on the IP protocol. However, for data transmission,, it uses the RTP (Real-time Transport Protocol), which transmits information in real-time. SIP (Session Initiation Protocol) – the dominant signaling protocol, is also used very often.

It is safe to say that in practice, VoIP phones are used in exactly the same way as analog phones. However, they have additional functions that can be very useful, especially in a business environment. Thanks to VoIP, it is possible to manage the entire fleet of phones from one account. This applies not only to numbers but also to entire address books, redirection between departments. 

Most landlines require a connection to power and an Ethernet network. Cordless telephones require a docking station to be connected to the power supply, which most often connects wirelessly to the DECT station (module for wireless calls). The modem or router must be equipped with it. It can also be connected as a separate device. And what kind of Internet will be needed to use VoIP freely and freely?

Importantly, not only the transfer speed and data reserve are important, but also the stability of the link. This is possible thanks to the appropriate codecs and settings. To work properly, VoIP telephony always needs the same stable speed for both sending and downloading packets. Much depends on the individual offer, but it can be said that such a universal parameter will be 40 kbit / s, and in the case of the international standard – 64 kbit / s. It is known that on the market, you can get offers for much greater values, but most often only for downloading. Besides, it must be remembered that this speed can be different when we take into account atmospheric factors, location, etc. In the case of VoIP, the main problem is, therefore, not the speed but the quality of the connection. It is also often the biggest challenge for companies.

VOIP phones - why is it worth it?

As we mentioned, on the one hand, VoIP phones are not much different from traditional landline phones. Especially in terms of appearance. However, they differ in the lack of connection to the telephone network, which also brings certain benefits. Starting with the absence of cables tangling around the office. The installation of the phone itself is very simple and usually does not require additional help from specialists. We also do not need any additional equipment. The servers of the virtual exchange are occupied by the IP telephony operator, and only the Internet connection and the PBX configuration are required to start the phones. As a result, the costs of implementing a telephone exchange are much lower.

The most important reason to consider switching to VoIP is the price and quality of calls. First of all, there are no subscription fees, and calls within VoIP telephony are free of charge. Fees will appear only for international calls. Additional costs are also eliminated, problems are solved with the help of updates without the need for technical support and outsourcing service. Instead, you gain ongoing access to all users and the possibility of even better organization of your corporate communication. VOIP phones work through individual user accounts or SIP addresses. This means that when one user is busy, the telephony changes the connection to the next person. The ability to freely manage conversations significantly improves the organization of communication.

IP phones work well in even larger and more complex environments and companies. Mainly due to its flexibility and scalability. A large number of users is not an obstacle. Of course, if we take care of the appropriate parameters and implementation tailored to the individual conditions of the company. For our part, as always, we encourage you to invest in new technologies. Will VoIP be one of them – we leave this decision up to you. It is definitely worth considering the implementation of this technology in the case of sales companies, companies from the call center industry, or environments with an extensive customer service office. In addition, there are many indications that in a few years, there will be no more choice, and VoIP telephony will be the new, universally applicable standard.
