I have bough TDM400P Wildcard and I have installed Asterisk on Red Hat. I have configured several basic configuration files (extensions.conf, iax.conf, modfem.conf, modules.conf, phone.conf, sip.conf, zapata.conf and zaptel.conf). When I run asterisk and pick up telephone line that is plugged in Channel 1 (FXS channel with FXO signaling), I don’t hear any dial tone. Asterisk (in CLI) doesn’t show any information that I have picked up my telephone.
Is the hardware error or I need to configure something else?
