Thanks for your response. You’re spot on, but what I’m wondering is if its possible to use the hardware I already have as an ATA by configuring FreePBX somehow.
Can my raspberry pi with its FXO port module (Switchpi OAKR2 module) perform the same function as an SPA3102 ATA by configuring FreePBX? I would have thought it could, but I might be mistaken.
Only problem is with buying the SPA3102 is (besides having to purchase more hardware) that I’ll need to plug in directly into my router with an ethernet cable. My apartment has the FXS port and the internet (cable) connection on opposite sides of the apartment, through two doorways. I’d like to avoid passing an ethernet cable through the house and doorways (can’t drill holes either, not allowed) so I wanted the VOIP part to be passed over WiFi (I know, not the most optimal connection but its just for the buzzer so I don’t mind).
Thanks for your help.
