When it is necessary to connect two PBXs (and not every person has certain knowledge in this area), this business is entrusted to specialists. However, if you think that you can do this work yourself, read the detailed instructions and it will help you quickly and competently connect two PBXs.
Instructions
Step 1
For example, it is not at all difficult to connect two Panasonic PBXs to each other. To do this, connect on one of the PBXs to the analog input port, and on the other - to the internal analog port.
Step 2
After that, to call from the number of the first PBX to the number of the second one, dial the line access code (for example, 81) and then the extension number. Dial the extension number on the other PBX. In order to be able to dial 81-extension number in both cases, connect them with two wires. Thus, for a two-way connection, you need a mini-PBX with two external lines (or CO).
Step 3
PBX programming allows you to make it possible from internal numbers to access your CO line exclusively, as well as to perform a similar procedure with the numbers of the second PBX. If you do not like this option, install a special billing program.
Step 4
You can also link two PBXs located in different cities. To do this, you need a corporate communication channel. A signal is transmitted over this channel without any problems. If necessary, use one of the companies specializing in sending over the internet ypn.
Step 5
For this:
- stretch the VPN over the Internet;
- connect your PBX to VPN;
- reprogram the PBX a little.
Step 6
Another connection option is also possible. For it, you need a high-quality Internet provider and two VoIP gateways. There are many ways to connect these gateways. The simplest is to contact the manufacturer of the main installed PBX or your store clerk and purchase an additional fee for VoIP support. It will allow the transmission of telephone traffic directly to the IP network.
But this method has some disadvantages. For example, not all PBXs have the ability to expand; the price of a proprietary board can reach several thousand dollars. The company that will serve you will also charge decent money for reprogramming the PBX.
Step 7
To solve this problem, buy and connect an additional device - SIP gateway (VoIP gateway). Panasonic PBX can work with other PBXs as well. To do this, in some cases, due to different voltages, you will need to buy an adapter.
