Outbound and Inbound Calls using JUST PSTN line as a trunk

Hi voip experts,

Please help me with my newbie problem in settin-up my voip(asterisk) machine. I have this TDM400P with 2 fxs and 2 fxo. I already installed AAH2.8, all is well i can say because i can do a call between my extensions using a softphone (xlite). My concern now is how to do outbound calls and incoming (to local PSTN line). Im a newbie so dont know what to do next. i’ve read this Dumbme guide to setup trunks & routes but it seems that the tutorial is concern about VSP (Voip Service Provider) which is i dont have. My ONLY RESOURCES is an PSTN line connected to my TDM400P (fxs). Correct me if im wrong, but its possible to setup a trunk from a PSTN line (without using a VSP service), right?Now the questions, how can i create a trunk and route to do outboud and inbound call (to local PSTN line)?Where to start? Please guide me with this experts…Thanks in advance…

kind regards,

Keep reading the DumbMe guide. There is a chapter (9) that describes this very thing.
