Hello,First excuse any mistakes in English. I'm working on a platform that makes use of integrated Kamailio with asterisk (Elastix mt).This platform allows the login of my SIP clients via the extension number and the client's domain, where the kamailio after authentication change the username to sip EXTENSION + _ + DOMAIN (expected by Asterisk) and sends to the asterisk.I need the client can also send the sip user in standard EXTENSION + _ + DOMAIN, for it changed the view subscriber to also return a username record in the format that the softphone is sending, but the platform still seems not authenticate the REGISTER using new way functions in auth_check ("$ FD", "subscriber", "0") and auth_challenge ("$ FD", "0").Thus works:Login: 101Domain/server: pabx999999.ligou.mePassword: PASSWORD_PLAINThis way does not work:Login: 101_pabx999999.ligou.meDomain/server: pabx999999.ligou.mePassword: PASSWORD_PLAINAlready got a good look at the documentation and could not find the problem, could give me some help?Kamailio.cfg: http://pasted.co/db8fb3a2Execution debug log: http://pasted.co/49bfe5bfContents view subscriber:+-----------------------------+---------------------+---------------+------+| username | domain | ha1 | ha1b |+-----------------------------+---------------------+---------------+------+| admin | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || adminIM | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 101 | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 103 | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 103IM | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || admin_pabx999999.ligou.me | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || adminIM_pabx999999.ligou.me | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 101_pabx999999.ligou.me | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 103_pabx999999.ligou.me | pabx999999.ligou.me | PASSWORD_PLAIN| NULL || 103IM_pabx999999.ligou.me | pabx999999.ligou.me | PASSWORD_PLAIN| NULL |--------------------------------------------Bruno H.
