asterisk users - Aug 2018 - 401 unauthorized

hi

I have a connection to a cisco all manager SIP trunk. The first call coming
across CCM to the asterisk server works fine... Then when I do a second
call from CCM to asterisk  I am getting a SIP 401 unauthorized.

My definition is simple.
[CCM]
type=friend
dtmfmode=rfc2833
username=CCM
defaultuser=CCM
disallow=all
allow=ulaw
allow=alaw
context=smvoice-incoming
host=X.X.X.X
canreinvite=yes
qualify=yes

This is asterisk 13.19.0

What is wrong? Thanks

Jerry

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.
