10 Popular IP/SIP Phone Brands & Models to buy for your IP PBX


What is an IP Phone?

Quite simply, IP Phone is a telephone that plugs into your network port (RJ-45), instead of the telephone port (RJ-11). It connects to, and uses the computer network to transmit voice (and data), unlike analog phones that use a dedicated telephony network. If you want to use IP Phones on your network, you need an IP PBX to control, coordinate and interface with various telephony components. If you are new to VOIP, do read this ‘Introduction to the various components of a VOIP system’ article, that I wrote sometime back. You might also want to take a look at the ‘Advantages & Limitations of IP Phones’ article as well.

In this post, let us have a look at 10 IP/SIP Phone brands (and a few models for each brand) that you could buy for your office/organization. Please note that this list does not follow any specific order and it is in no way exhaustive. The brands/models mentioned here are popular IP/SIP phones, but there are many more brands/models available in the market. These IP phones are mostly entry to mid range, meant for business applications. You should be able to see the price of each IP/SIP phone mentioned below (in USD) and you can click on the link/graphic given below (for each phone) to learn more/buy them from Amazon, if you live in the United States (US).

10 IP/SIP Phone brands/models to consider/buy for your IP PBX –

Please note: SIP is the open standard protocol for VOIP communications and it is supported by most IP PBX models. Some phone models mentioned below may have separate SIP phone models (that work with any SIP compatible PBX) and separate IP phone models (that work only with their own IP PBX models).

Most of the phones mentioned below support SIP, but do check once before buying. Also, not all the below mentioned phones come with power supply. If you intend to use POE switches/POE adapters, power supply may not be required. Otherwise, you will need it. If it is not included, you can buy the power supply separately.
