New sip soft phone problem with pasword,

Hi, I started again to work with asterisk, I must create trunk between Asterisk 11 and CUCM 10.5, for now I want only to create a few users on asterisk, I created in sip.conf, but I have problem with password. o.O. I used and username but everything is the same :frowning:.

I do not know what to do…grrrrr

NOTICE[28776]: chan_sip.c:28062 handle_request_register: Registration from '<sip:8408@>' failed for '' - Wrong password

What if you use a SIP Peer with not authentication and registration? Can you set up CUCM for this?
