How to connect the extension numbers of headquarters and branch offices through ippbx

1. First, we find a way to connect the IPPBX with the voice gateway, and then we connect the analog line from the voice gateway to the external port of the ordinary telephone exchange.

If you want to call the extension of analog telephone from the extension of IPPBX, for example, the extension numbers we gave to the simulator are 805 and 806, then you can dial 805 directly to the old telephone exchange. If this external port is opened and the computer operator function is realized, you can dial the extension to the position of the designated colleague.

3, analog telephone exchange, to call the IP side, you can directly choose the outside way to call, you can also use the multi-office scheme. For example, we usually dial 9 to take an analog outside line. We can set 6 to get the signal of the IP end, and then dial the extension number of the IP end directly.
