Thats why its usually recommended to go with IP-Authentication only. Send INVITE and Provider says Lets do this call,simple and easy. From the configuration perspective this is my idea of still using UAC. - Call coming from FS on kamailio - Rewrite the from-uri (so the provider receives calls from the registered username) - modify the to-domain part to contain the IP address of the provider - set the $du to ip of the provider, and t_relay() the call. - Most likely the Provider would say Proxy-Auth required..that can be caught in failure_route[] - There you can call the uac_auth() function to have username.password attached to the response of above. http://kamailio.org/docs/modules/4.3.x/modules/uac.html#uac.f.uac_auth() - once this function is successful send the INVITE again to the provider. Last three steps can be the following snippet of code(reference from here): failure_route[2] { if (t_check_status("40[17]")) { xlog("got challenged \n"); if (uac_auth()) { xlog("auth was succesful \n"); t_relay("udp:ip_addr:5060"); //provider's IP_ADDR } } I hope you get IP Auth from the provider, and find the reply useful.
