What is important when buying office phones?

In principle, today’s office phones must be able to work with IP telephony. This is because almost all communication is now done over the Internet and not through traditional telephone lines. However, it is important to know that today’s business phone models have multiple utilities, prices and functionalities.

Businessmen should make a balance between cost, benefit and also functionality when buying their phones. Of course, not all the budget can be spent on equipment purchases when it comes to a company. So, the first thing to do is to rationalize purchases and to do so, the functions of the phones must be known.

Another question buyers should ask themselves is: What do I need this phone for? This is key because with a simple analysis it will be possible to economize the budget allocated for this purchase. Each model has a different function and should be oriented to a certain role within the company.

This means that a small office can solve its telephone communication by means of this product. This is ideal, because eight different calls can be made simultaneously in the same environment. This is ideal, for example, for large-scale providers.  The cost of the unit with the base is 109.90 €.

Another similar but slightly more expensive model is the Yealink T58A, with a large touch screen. This phone allows video conferencing and has a CAM50 camera precisely for these purposes. It costs 235.90 and offers all the features an executive needs. This is one of the best Yealink terminals on the market.

The most expensive models of Yealink terminals

Some devices far exceed the functionalities of those already mentioned. Of course, this type of device is necessary in large companies, or those dedicated to technological innovation. Below, you will see the cream of the crop of IP telephony for the business world.

Of course, everything will depend on the requirements of the buyer and the use to which the devices will be put. It is all a matter of verifying the budget you have to make the purchase and choosing a functional option.

Buying on a budget

The best thing about IP telephony business devices is that there are many different options. The buyer can always review the specifications of each device and weigh the costs of each. The important thing when making this type of investment is to think about the needs of the work team.

Not every office needs to have state-of-the-art devices with cameras and color screens. This is the part that the purchasing manager or entrepreneur should check. Just take a look at each department and understand their particular requirements. In this way, costs can be reduced and still opt for quality equipment.

In any case, the most vital thing is to be able to upgrade the company so that all communication works by IP telephony. This is the goal to be achieved and there are always viable alternatives to reduce costs. For example, some departments can resort to the installation of Grandstream Gateways. This allows some not-so-new devices to make and receive calls over the Internet connection.

Yealink terminals: The evolution of IP terminals

An IP terminal is a device that allows the connection of voice through internet protocol (VoIP), to be able to have a call as if it were a conventional call, Yealink terminals are the models available in the market with the most advanced technology, practical and economical.

What is Internet Protocol or VoIP?


The internet protocol or VoIP (the one used by yealink terminals), are a series of resources that allow voice communication through the internet.

telefonía ip

This protocol allows the transformation of voice to data packets (unlike traditional telephony which is analog), ie transforming the analog call in digital to be transported over the Internet.


Differences between VoIP and IP telephony.

When you are talking about IP terminals you must make the difference between VoIP and IP telephony, for some it seems the same, but the truth is they are not, we present the differences below.


  • VoIP:

These are the standards, protocol and technology used by devices to transmit voice digitally. There are no calls, information, services or gateways.

  • Telephony over IP

Services that are available for use by the public, these are based on VoIP protocols.

How does internet protocol work in yealink terminals?

To be able to have a communication based on voice technology over the Internet you need a client, a server and a Grandstream Gateway, below we explain in detail each of them:

The client

In order to carry out calls, there must be information input (user’s microphone), it is encoded, packaged and transmitted over the network and reaches the IP terminal where it is decoded, unpacked and played at the output (yealink terminal speakers).


Who can be the client?

Skype or a company that offers IP telephony services using analogue telephone adapters or software for this type of communication (Softphones).


IP servers or switches are responsible for managing the database to account, collect, route, administer and control the service.

In these switches are installed software that operate all the information, allowing communication between 2 VoIP devices or between a VoIP and a conventional telephone.


Gateways grandstream

Grandstream gateways enable communication between users. Their main function is to provide connection with traditional telephony, functioning as a platform for virtual users (clients).

The gateways are used to terminate the call, in this way: the user initiates the call and it is terminated by the gateway granstream.

Many small or medium sized companies that have PBXs can use this technology not to replace it.


Advantages of VoIP Calls


There are a variety of advantages, among which they stand out:


  • Avoid long distance telephone charges (domestic and international).
  • Lower bandwidth required (compared to use of other mobile technologies)

Disadvantages of VoIP Calls

Among the disadvantages we have:

  • Lower call quality (latency, delay)
  • Ease of data theft (due to lack of system security).
  • Probability of virus infestation in the system (as there is no antivirus in the system).


What is a Yealink terminal?


The yealink terminals are digital devices that allow you to make voice and video calls using the VoIP protocol, using a local network or through the use of the Internet.

In many opportunities they present more advantages and options than the traditional telephony, multiple lines, digital cameras, color screens, capacity of wireless connection to fixed devices (bluetooth).


How to choose the best Yealink terminal?


Among the basic features necessary for choosing the best terminal yealink are the amount of lines you need, merit a color screen, what configurations you need, sound capacity, has voicemail, has access to video conferences, which network to connect.

These options will determine how complex should be the yealink terminal to choose, in Neotel 2000 we offer the best consultants to help you get the one that best suits your needs.



What determines the choice of yealink terminal?


Below you will find a list of features that are determinant when choosing your yealink terminal.

Yealink terminal costs

For many companies determining terminal costs will be essential when purchasing an IP phone. Entrepreneurs are enemies of unnecessary expenses.

VoIP telephony will lead to significant savings, but be careful if you choose the wrong yealink terminal, choose one of inferior quality or few configurable will lead to headaches.

The best available sound must be guaranteed in the devices to acquire.



The style that you need for your office, home or vehicle can be different style, can include wireless yealink terminals (similar to mobile devices) which merit to be powered from an electrical source.

Another stylistic situation is the need for a color screen for video conferencing, quick menu access buttons, pre-selected calls or receiving voice memos.



Quality may depend on shapes and sizes, many have been found in the market since VoIP appeared.

The quality of yealink terminal can be determined by the time in the market, the guarantee they offer.


Service Provider

The choice of service provider can make a big difference in getting the most out of the full-featured VoIP device, or just the most basic ones.

We must remember that VoIP telephony allows to feed several phones. Each of the telephones will connect directly to the internet, therefore a secure connection is necessary.

You must make sure that the service provider is compatible with all the features of your yealink terminal.

Yealink terminals and grandstream gateways evolve the way they communicate

It is becoming increasingly important for companies to maintain close communication with their customers. One of the most effective ways to achieve this is through call centers. To ensure the proper functioning and reduce operating costs of these centers, companies can occupy devices such as Yealink terminals and grandstream gateways. If you are not very familiar with these issues, we invite you to continue reading this article, because we will explain to you what each of these concepts are.

In the first place, it is worth mentioning that call centers operate on the primacy of providing a means of communication between companies and customers and suppliers. Some function as a customer service center, to provide advice or help of any kind. In this case, they are called incoming call centers, because it is mainly the clients who contact the call center. On the other hand, there is also the modality of sceptres of outgoing calls, whose purpose is usually to contact the largest number of potential customers. However, technology has changed the way these centers work.


The Yealink terminals and the location of call centers

Traditionally, staff working in call centers were gathered in the same geographic location, as in a room adapted for this purpose. But technology has evolved this way of working. And it is at this point where Yealink terminals play an important role.

Yealink terminals are basically IP phones. And what is an IP phone? It is a device that allows you to make calls using the Internet through a virtual pbx, instead of the ordinary telephone network. This allows to reduce the cost of billing for telephony.

But it also has other advantages, such as the ease of linking calls to almost anywhere. For example, with Yealink terminals it is possible to link received calls with an employee or a partner who is located in another geographical area. This means that if the call center is in Spain, you can easily link the call to be answered by your partner in South America (for example).

But what if you don’t have an IP phone and you don’t want to invest in acquiring some, and you already have many traditional phones? In that case, you can use the grandstream gateways. What are they and how do they work?
