I have two PBX telephones. Each one has a line cables to the houses, but there is no connection between these two pbx telephones, neither wire nor wireless. How can I join between them wirelessly? What equipment should I buy?
There are many possible answers. In your place I did the following:
- I would buy 2 analog telephone voip adapters (at most some tens of dollars). Putting them to the phones, from now you have IP connection.
- Buy two wireless routers (some tens of dollars). Connect them with static IP addresses and routes.
- Optionally, if you also don't have power, then you can buy solar panels (thousands of dollars) and a UPS (hundreds of dollars). But the first is costly, maybe a mechanical battery charger would be significantly cheaper (some hundred dollars).
The whole thing would cost around some hundreds dollars if you don't have power, but yo can solve this even below \$100 if you have.
The main disadvantage of this system is that the range of the wireless router is short.
