Telephones for IP-telephony

To work with Internet telephony, you will need IP phones, softphones, FMC or VoIP gateways, which we will discuss in this article.

Soft phones (softphones)

Soft phones (softphones) – programs that allow you to make a full phone from a computer, headphones and a microphone with a convenient and intuitive interface.


WebRTC is a technology for making calls from the browser, which is implemented in IP PBX via the built-in softphone CRM and allows you to call one click.

IP Phones
IP telephones are handsets with a handset and dialing buttons that differ from analog phones using the Internet via SIP protocol. They allow you to transfer a call, put it on hold, use a speakerphone, connect a headset and much more.

Such phones fall into two categories:

Based on our experience, we can identify 4 models – Cisco SPA 303, Yealink SIP-T21P, Panasonic TGP500 and Yealink W52P.

Cisco SPA 303

A reliable wired device that is deservedly popular with users of IP-telephony.

The average price for June 2017 is – 6500 rubles.

One of the leaders in the market of wireless IP-phones. It has an advanced version of Panasonic TGP600, which differs by the increased number of connected lines supported by the base of the tubes and the color display.

FMC cards are special SIM cards that turn a mobile phone into a wireless IP phone, but which will work not through the Internet, but through GSM.

The advantage of this technology is that the employee is not attached to the office, but can work fully in any place where there is cellular communication. For outbound calls, customers will see the company number rather than the employee’s mobile number.

All conversations are recorded in the PBX and in the CRM with which they are working. And free calls between employees will help save on communication.
