Re: [Serusers] SER and Voip Provider integration for call PSTN phones

I'm looking for SER "uac modules", but how to configure ser.cfg to use it? Could anyone help me? Thanks. Hi to all, I have deployed SER on public IP, and i can install a communication betwen two IP Voip client. Now i want configure SER to call , from a IP VOIP Client, PSTN phone number. I' havent a PSTN gateway but I have a Voip Provider Account (Eutelia www.eutelia.it) that require authentication in order to call PSTN phone. I'm studing the PSTN configuration reported in SER getting start (http://siprouter.onsip.org/doc/gettingstarted/ch09.html) It describe how to use rewritehost("XXX.XXX.XXX.XXX") to specify the PSTN GATEWAY IP ADDRESS, but doesn't specify nothing about authentication. The question is : Because i havent a PSTN gateway, It' is possible to configure SER in order to redirect PSTN call to a VOIP provider or It is necessary to use Asterisk between SER and the Voip Provider ? Any suggestion about ser configuration would be appreciate. Thanks in advance.
