I've an issue with a patton 4114 with 2fxo and 2fxs ports onboard. I configured the 2fxo ports as a double sip trunk into free 3cx pbx and the 2 fxs ports are configured to be pdx extensions. The extensions are correctly registered into 3cx but I'm unable to make calls from the analog phones connected to the fxs. I digit the telefone number but after a long silence I obtane i unavaiable line tone. In attachment i put the configuration file of patton, the putty log of a failed call and 3cx server log.
