Hello, I have a problem with multiple domains. [WARNING] sofia_reg.c:1251 sofia_reg_parse_auth() can't find user [cstomi@192.168.1.37] You must define a domain called '192.168.1.37' in your directory and add a user with the id="cstomi" attribute and you must configure your device to use the proper domain in it's authentication credentials. [DEBUG] sofia_reg.c:705 sofia_reg_handle_register() send challange for [10@192.168.1.37] I have multiple domains in the directory, and put the user under the proper domain. <domain name="test"> <user id="cstomi"> <params> <param name="password" value="cstomi"/> </params> </user> </domain> But I can't configure the client device (another FS) to use this domain in INVITEs, REGISTER is fine. I saw the to domain is used in the realm of the challange, what determine the domain in the directory, isn't it? my gateway settings: <gateway name="test"> <param name="realm" value="test"/> <param name="username" value="cstomi"/> <param name="password" value="cstomi"/> <param name="extension" value="inbound"/> <param name="proxy" value="192.168.1.37:5060"/> <param name="expire-seconds" value="600"/> </gateway> REGISTER: It seems the to host is made from the realm...I'm not sure.. So it works, I don't get the WARNING above. but in INVITE the to host is seems to be the "proxy". I guess if I could change the to host, authorization would work...How could I do this? Thanks any help, Tamas
