Hi, I have a setup where asterisk (1.4.18) is connected to a SIP proxy. Now the SIP proxy challenges REGISTER and INVITE request from Asterisk. Asterisk is able to handle REGISTER request challenge but for INVITE request, it seems to handle authentication for only one user that exists under the global authentication. Even if I configure all users in global authentication, asterisk is using only the first username:password pair for that realm (realm and domain is same for all users). Can anyone help me understand why this is happening and if there is solution? Regards, Mayur -------------- next part -------------- An HTML attachment was scrubbed...
