Hi all. I am using the library Microsoft RTC to connect a windows software with * in a local network via SIP. In my sip.conf I have defined a 'friend' for this software with their username and their password. I don't want that nobody can be connected without the password. When I call to * it says: "Proxy Authentication Required" in the SIP debug. Please somebody can tell me how to authenticate from RTC to *. Thanks. Blas. --------------------------------------------------------- Ahora en tu móvil puedes llevar la foto que tú quieras: http://logos.ya.com/SLogo?M=phototomovil Ya.com ADSL Router Wi-Fi: Sólo 29,90 €/mes + IVA*.
