chan_sip.c:27919 handle_request_register: Registration from """"" - Wrong password

I installed Freebx 2.11 with ASterisk on debian 7.0.1 64bits, I m’ trying to register the extension in the PBX and the output is this:
Sep 3 10:23:02] NOTICE[8016]: chan_sip.c:27919 handle_request_register: Registration from ‘"7400"sip:[email protected]:5060’ failed for ‘192.168.157.244:3731’ - Wrong password

need help

I think that: file /etc/extensions.conf have not overive by file in extensions.conf of freepbx. There are 1 in 2 way:

  1. You need build freepbx
    Firt
    cd /etc/asterisk
    rm -f extensions.conf features.conf iax.conf logger.conf sip_notify.conf sip.conf

Then cd …/freepbx-**
./install_amp
Reboot asterisk.

  1. Other
    cd /etc/asterisk
    rm -f extensions.conf features.conf iax.conf logger.conf sip_notify.conf sip.conf

copy (or link) all file from /var/www/html/admin/modules/core/etc to /etc/asterisk

Context ‘app-callwaiting-cwon’ tries to include nonexistent context 'app-callwaiting-cwon-custom

trunks register, but no phones
