Hi, I have a subtle problem, with videotron sip provider. If I use ip address of server, I can connect and authenticate. But when I use full name, I receive message "403 Forbidden", I join messages below. Videotron uses outbound proxy, but when I define this parameter, I get the same message. Do you have an idea to resolve or localize this problem ?
