SIP registration failed - wrong password

Hi guys,

I have asterisk on my server which in the Internet. I try to connect to it with two different sip phones (zoiper and x-lite) but I got always the same registration fail because of wrong password!

This is my sip.conf file:
[general]
context=internas
allow=all
qualify=yes
port=5060
bindaddr=0.0.0.0
dtmfmode=rfc2833

[3000]
username=3000
secret=1234
host=dynamic
type=friend
nat=no

Then I use the same username (3000) and password (1234) in my sip phone (both of them are behind the NAT), but I always get this error.

NOTICE[2734]: chan_sip.c:28236 handle_request_register: Registration from ‘sip:3000@142.150.XXX.XXX’ failed for ‘132.205.XXX.XXX:56354’ - Wrong password
Scheduling destruction of SIP dialog ‘76589MTUyODA2MjE5YWY1MWJhMTc0Yjc1MmQ5NTQ2NTNiNTA’ in 32000 ms (Method: REGISTER)

I read a lot about it but I can not solve this issue. Would you please help me to find where is the problem?

You are using the wrong password!
