Hi Michael, Thanks for the response, it worked in the opposite direction, the gate controller (OOB) calls phones (Inband) kind of like the door thing on an apartment block. Start_dtmf worked if I called the gate controller from the phones, but not in the other direction which is how it will be used. It has been resolved as it was discovered the ATA devices inbuilt to the fibre ONT have an option for OOB DTMF, enabling this on the POTS profile allowed the device to function. I am still interested on how I could of got it to work though, is start_dtmf a one directional app?

Also, pastebin the console debug output for a call to the gate controller where you press digits but the controller doesn't respond.

Rather than out the b-leg.. It works fine when I call a SPA502g as it will provide RFC 2833.. is there some trickery I can achieve this? Or am I just doing it wrong??
