Thanks Marc, so in the following module what happens if either 1 or -1 is returned?

#!ifdef WITH_PSTN
route[FROMPSTN] {
        if($si==$sel(cfg_get.pstn.gw_ip))
                return 1;
        return -1;
}
#!endif


Thank you,
A

It's checking the source of the current message.  If the source address of the message equals the variable pstn.gw_ip, return 1, otherwise return -1;

This is a very basic question, but can someone let me know what this line means?

if($si==$sel(cfg_get.pstn.gw_ip))
                return 1;
        return -1;


Thank you,
