[Freeswitch-users] Freeswitch User Adding

Hello, I have problems with adding new user to freeswitch. When trying to add user with user id has different number of digits than 4, it can register but it cant call or cant be called. I changed local extension regular expression in dialpan default.xml but the changes only work with four digits users(user ids or dial number) .So I want dial a number that has five or more digits. What other configurations I must change. Thank you... Burak,
