The reason why the CM is asking for authentication is outside the scope
of asterisk, debug the CM. Since you have no secret set for the user,
asterisk will never try to respond to a challenge. Asterisk and CM can
work together, asterisk is very forgiving, CM is not. The last time I
had to figure out what the fromuser and fromdomain should be (the CM admins
were clueless about providing those facts) and there was some
throtteling mechanism that when triggered would deny any SIP messages.

Good luck.
