[asterisk-users] Strange SIP packet

Hi, everyone.
I'm testing a SIP cable modem with asterisk. The REGISTER packet it
sends has varios "Authorization" sections, which I have never seen
before. Asterisk sends back "401 Unauthorized". I've checked
username
and password both in cable modem config and in asterisk sip.conf. They
are correct. So, is the reason for "401 Unauthorized" those multiple
"Authorization" sections? If anyone is more or less familiar with SIP,
please could you take a look at the packet trace below. Is it ok?
Thanks in advance.
