is there a comprehensive guide for configuring freepbx with Fritzbox 7590? I have freepbx installed on raspberry pi 4 and want to create a voiP menu that forwards to 2 numbers. I then want to connect the rasperry pi with the fritzbox. since the goal is to give the caller multiple options of extension. For example: Press 1 for accounting, press 2 for a sales person, etc. If the caller does not press anything, then he should not be forwarded.
thanks in advance
