Choosing an IP phone?

Question

Asterisk

Colleagues, tell me about the choice of piece of iron. I myself practically did not deal with the issue, so I am a teapot in it. There are a number of phones for organizing communication between branches, they sit in a closed network, a serious VPN with hardware encryption - well, that’s not the point. The task of phones is SIP point-to-point communication, it can be with video, it can be without. There are no conferences, no server there, never was and never will be.
Question - tell me the model of the device that accurately supports point-to-point communication, indicating the IP address you need to call? And that was already an incident, the guys bought some Cisco without thinking, which, apparently, can’t work without a server - I asked for SIP support, but I didn’t find the opportunity to address the call directly to another device.

Answer 1

Cisco SPA504G: sip-firmware is immediately installed, it is managed remarkably through the web interface, all basic functions work fine, localization is normal. What does sip point to point mean?

Answer 2

If it's not a secret: what is the purpose of such a task? You understand that from the point of view of administration it will be a nightmare?

Answer 3

If budgets allow, then Polycom has a whole line of video terminals:
