Hi everyone, I have gone through the articles in this list regarding asterist and ser but I am still confused. I have setup ser and can forward a call to a PSTN. I need to know the following: 1. Is it possible to do prepaid billing using ser? or should I use asterisk with ser? 2. If I need to use asterisk then please tell me where I can find details (possibly step by step info) on how I can setup asterisk and ser to do prepaid billing. Thanks. __________________________________ Do you Yahoo!? Meet the all-new My Yahoo! - Try it today! http://my.yahoo.com
