What phones to choose for sip-telephony?

Question

Telephony

Good afternoon everyone. Need advice and / or links to read. The office decided to move away from conventional telephony to SIP from our own telephone operator. We need advice on devices, possible functionality, etc. The PBX itself (virtual PBX based on asterisk) is provided by the telephone company, that is, we only need to deploy a router to connect and the handsets themselves.
I have never encountered this even as a user, so I don’t have a very good idea of ​​​​what it is all about. What are there? WiFi or wired? If by wire, it turns out that to each workplace to pull additional. wires? What can they do? How much are?
In general, we need an educational program on the topic. Thank you.

Answer 1

Forget wifi. You will not find an inexpensive solution and stable work.
For devices, pay attention to Yealink. Cheap and cheerful. Years of stable work speak for themselves.

Answer 2

The main difference between wired phones is .. number of ports! If two - then the wire from the network to the phone. and from him to the computer. Can take power from the switch over PoE. maybe from the power supply. The rest is not important. Good Panasonic.

Answer 3

If the workstations are computerized and already included in the general network), then it is enough to install any SIP dialer on the computer and connect a microphone with headphones - nothing else is required.
wi-fi can be a problem if there are a lot of wi-fi access points around.
