Hi all, I add user using serctl like: #serctl add 123456 pwd123456 123456(a)iptel.org But when I use check_from, it always return fail. And the from is like 123456 <sip:123456@iptel.org>. I wonder what need to be add in datebase and how to add it. Maybe I need add alias using "serctl alias add 123456 sip:123456@iptel.org" ? Jimmy
