I have more than two phones (3 obi 1032 phones). I also have 3 GV numbers on those phones. I want to connect the phones together so that when anyone calls any phone regardless of the number they call I can see that someone is on that line (if that's a good idea).
I also want to install an auto attendant the greets the customer first thing when they call (with more options than the stock obitalk one). I have downloaded and install FreePBX on a raspberry pi 3B+. I am looking for some direction with this. This is the last piece of my upgrade project. By the way one of the phones is going to be in my home office. I need it all to work together. Thank you in advance.
