Hi, I've got a question which may or may not have been answered earlier. I'm running ser-0.9.0 with two domains, <domain-a> and <domain-b>. (serctl domain add <domain-a>/<domain-b>) I've added <user-a>@<domain-a> with password <password-a> (serctl add <user-a>@<domain-a> <password-a> <email> Both modules registrar and userloc has use_domain=1 Default SIP_DOMAIN="<domain-a>" Registration with <user-a>@<domain-a> and password <password-a> works, as usual, fine. If I modify my user to register as: <user-a>@<domain-b> and password <password-a> and it still is registers OK! Is this how it should work? I would expect that the client should not be able to register using another realm... Best regards, Helge Waastad
