[Serusers] help with SER on Solaris 10 and softphone on Win2000

[Gould, Aaron]

i have a softphone on a windows 2000 laptop
 
after the softphone sends a "register" message to SER, i see on the sniffer that SER sends a "register" message right back to the laptop.  is this normal?  and i see next that the laptop sends a SIP 405 "Method Not Allowed" message and that the SER sends the same thing back to the laptop
 
what does this mean?
