Hello everyone, hope you can help me. What I have? I have a PSTN Line and a SPA3102 (1 FXS and 1 FXO). What I need? Example: “Client A” wants to call through my PSTN Line. He calls my VOIP NUMBER, he enters a “Secret-Code (+-12 digits)” and he has access to my PSTN Line. From there he can call Local numbers. I want to control the amount of minutes he can talk. And if possible control the numbers “Client A” can reach. Is this possible? How? What do you recommend? Thanks!
