How to connect and configure PBX Panasonic kx-hts824 and connect eight hdv100 and one hdv230?

Question

Telephony

Good day!
A small office purchased equipment and refused to be set up by specialists, because isolation, quarantine, etc. (no money)
They hung everything on the employee that he was "fumbling".

What is available:
PBX Panasonic kx-hts824 with a standard board
eight hdv100 handsets
one hdv230 handset Call
recording server

Local equipment:
Eltex tau-1m.ip gateway, Asus RT-N12VP wi-fi router, d-link 1024 switch, d-link switch 1008, HiWatch DS-N104P video surveillance equipment + 4 cameras.

The main trunk is taken by Eltex, to which the only telephone is connected at the moment. An Asus router is connected to VoIP, on which the DHCP server is enabled. A d-link 1024 is connected to the router, which holds: 10 PCs, 3 printers and d-link 1008, on which there are cameras.

The hard workers opened all the boxes and threw out all the waste paper, including the manuals. I have not been able to find anything on the net except introductory pamphlets, and the links that contain the necessary material are protected by passwords.

I would be extremely grateful if those who know will tell what's what and in what order, or at least point a finger in the right direction.

Answer 1

The right direction - let the remote specialist set up without leaving your office, because isolation, quarantine, etc.
True, the option (there is no money) will not solve this.
