I downloaded the latest Ser 8.14 but I am having a hard time to get the standard ser.cfg that came with it to rewrite a host address so as to get PSTN access.

I am wondering if someone could enlighten me with a properly configured ser.cfg for PSTN access.  All of my attempts have failed sadly.  I can call and with in the network but as soon as I try to go a PSTN service provider it fails.

Many thanks
