Hi all, This is another question about NAT. When an user register a recorder will write to db.ser.location. If the user register again, there are another record writed. Maybe an user have more than one or two records in db.ser.location. What I want to do is that I want SER server call to SIP UA according the lastest record in the DB. So I set param of register: modparam("registrar", "desc_time_order", 1) so let SER server call the recently address of SIP UA registed from. And set: modparam("registrar", "append_branches", 0) to let SER server call only one address. And set modparam("registrar", "default_q", 50) to let SER server know which record is recently. I use SIP UA from a ADSL connection. Sometimes it worked. But sometimes, for a example, when ADSL restart and SIP UA just registed, I can see SER call to eldder address. for avoid this hapens, I set append_branches as 1. It make call slowly.
