VoiP Equipment

Popular Equipment for IP-Telephony


When you connect the phones at the office, you need to select the equipment. A variety of models, a rare replacement and a high price  – all this forces you to choose carefully. A study of our customers will show which equipment to purchase. Go to the section “What to choose?” And “Where to buy”, if you are looking for ready answers.

Initial data

  • The users-user section was made and analyzed. User-agent is a parameter that sends each SIP-phone or program to the PBX. Usually, it contains the name and version, for example, MicroSIP / 3.1.11. This approach is limited: you will not be able to recognize the model of the headset.
  • The sample includes 3210 users. Only those users who included the SIP client on the day of data collection came here. Who in another time zone or was at the weekend – the analysis is not included.
  • The evaluation was carried out only by quantity. Duration of use was not taken into account. If one user worked in different SIP-clients, then both were counted.

General conclusions

  • Apparatuses are much in demand than programs with a headset. A small share is occupied by analog gateways, they are needed when connecting previously purchased simple phones. The category “Other” includes FMC, software, and hardware automatic telephone exchanges.
  • Structure of the use of equipment: IP phones, softphones, and gateways
  • Two-thirds of all devices are wired and only a third of wireless. Softphones – softphones – are almost not used on mobile: their share is only 4%, and of the total number of SIP-clients – 1.5%.
  • Structure: wired and wireless phones, softphones and mobile SIP clients
  • Wired IP phones are twice as popular as wireless phones. If considered in general by SIP-clients, their shares are 31.5% and 16.1%, respectively. Now let’s take a closer look at the equipment.

IP Phones
Let’s find out which customers of SIP-equipment prefer.

Popular manufacturers of SIP equipment, distribution of shares

Expected for us, IP phones and Cisco / Linksys / Sipura gateways took the first place. We have united the companies into one brand because they belong to Cisco. Note: Cisco is developing its own line of equipment incompatible with SIP – choose specific models (below for more details).

Next, with a gap of two percent are located: Yealink, Panasonic, and Gigaset (Siemens). Every tenth device is Grandstream, this is the fifth place. At the end of the list of D-Link, their devices we do not recommend in principle. The group “Other” includes Eltex, Escene, Fanvil, Flyingvoice and Greenlite – they are too few to draw conclusions.

Wired (Stationary) IP Phones

Separately on wired telephones, the situation is changing slightly. The fixed phones of the companies Cisco and Yealink are in demand – these are the best devices on the market. Behind them are Grandstream and D-Link, 10% each.

Wireless (DECT) phones

We often recommend Panasonic, but Gigaset (Siemens) phones are in high demand – their share is 49%. Gigaset has more choices, so it’s easier to find a suitable option. The third and fourth place is occupied by Grandstream and Yealink, respectively.

Models of devices

Models of telephones are also divided into wired and wireless. The most popular stationary was Cisco SPA 303. This is a great model: reliable and easy to use. The market went out in 2011 and is still on sale. We created a configurator for it – you can configure any phone in three clicks.

The second most popular model is Yealink SIP-T21P. After the price increase for Cisco phones, we began to actively recommend Yealink – this is a good replacement for the price of half as much. If for some reason it does not suit you, look at the entire SIP-Txx line.

Manufacturer Model Quantity

  • Cisco SPA303 298
  • Yealink SIP-Txx 178
  • Yealink SIP-T21P 110
  • Cisco SPA5xx 82
  • Grandstream GXP1400 69

The leader among wireless phones was the Panasonic KX-TGP500. We also work with him for a long time and we recommend our clients. It is followed by two models Gigaset – A510 and C610A. If you are a supporter of Yealink, then look at the SIP-W52P model. While few clients use it, so the statistics did not accumulate.

Softphones and headsets
The chosen method of research does not allow to find out which type of headset the customers prefer. Therefore, we will consider software phones (softphones), and recommendations on models will be offered based on their experience.

Absolute leader – PhonerLite. PhonerLite uses 82.3% of our customers. The matter is that we offer to download the ready program which it is not necessary to adjust. If you are looking for an alternative, see the diagram below.

Popular software IP phones (softphones) without taking into account PhonerLite

Zoiper is implemented by our integrators, sometimes we advise if PhonerLite for some reason does not fit.

The telephone is a very simple client for working in Mac OS X. He has almost no alternatives.

Those who use softphones need a headset. About them we’ll talk below, now consider SIP-clients for smartphones.

Too few clients use SIP on smartphones – there will be no diagrams, tables or graphs. Just list the customers.

CSipSimple is the most popular softphone in Android. Immediately after it built-in SIP-client, as it turned out it does not work in all mobile. Acrobits and Bria customers use the iPhone.

Other equipment

Holders of analog phones prefer to save and do not change working devices. In this case, IP-gateways are suitable. They connect to the Internet and are configured as IP phones, but they have connectors for connecting ordinary phones. There are also disadvantages: IP-gateways are limited in the number of connected lines, the organization of telephony is complicated – the quality is falling.

The most popular gateways are Cisco. Models: SPA8000, SPA112 and SPA2102. The second place is Grandstream and its four-port model GXW-4004. GSM-gateways in this study, we do not affect, do not recommend them to use and do not consult.


Some customers register in the virtual PBX the existing hardware mini-PBX. Here, the unconditional leadership of Panasonic, but the reason for such popularity is not entirely pleasant. Panasonic uses the incompatible equipment. Who has already bought Panasonic PBX and phones to it, is forced to use further, so as not to buy new equipment.

If you are thinking of purchasing a PBX – think again, in order not to be in a similar situation.

What to choose?
Let’s make a resume that will help you choose. We distinguish four categories of SIP-equipment: headsets, gateways, fixed and wireless IP-telephones. Everyone has his own purpose and choice.


Use the headset when employees talk a lot on the phone: take incoming calls or call themselves. In our understanding, “a lot” is 5-6 hours a day, that is, more than half the working time. If they say less, then the headset is uncomfortable – you have to constantly take off and put on. The second advantage is price. USB-headset is cheaper than any IP-phone but requires a computer. If you work in CRM, then it already exists.

Recommended: Plantronics .Audio 622.

Stationary IP Phones

They are wired. It is convenient when you do not have to say much, and the employee sits in one place. A reliable device will last several years, will survive moving to another office, it will not be lost, and if necessary, you can connect a headset. This phone is easier to assign to an employee.

Recommended: Yealink SIP-T21P.

Wireless IP Phones

If employees speak a little and need mobility within the office – wireless phones (DECT) will do. Also, use wireless handsets when you do not need to attach an additional one to an employee. For example, one phone for the whole department.

Recommended: Panasonic KX-TGP500.


Focus on the gateways, if you already have regular phones. But do not try to save on them – you will lose more in quality. Our recommendations depend on the number of telephone ports you need. For two – Cisco SPA112, for four – Grandstream GXW-4008, for eight – Cisco SPA8000.

What do we use?

Technical support talks a lot with customers, so it uses USB headsets with a softphone. All Plantronics headsets of the Audio series models 622 or 628.

The manager and the head of technical support use IP-telephones Cisco SPA303, however, the manager’s phone is complemented by a wireless headset Plantronics W730, Savi.

The common office phone is the Panasonic KX-TGP500 wireless handset. She is alone and used as a telephone on duty to order an office pizza, for example.
