I guess the SIP show peer changed shortly after this.
The first message "Registration failed" means that your UA tried to register but couldn't
authenticate. This is how SIP works, first you send a REGISTER without auth, to get an
authentication challenge from the server. The next line "Registred SIP '114' indicates
that the UA took the challenge and sent another REGISTER, this time *with* authentication
and successfully registred.

A SIP ua that registers need to do this from time to time. You set interval in the phone
or in the sip.conf file. The sip.conf file takes precedence.
