[Serusers] kphone registration problem

[Jorge Merlino]

Hello:

I'm trying to register kphone to my ser proxy using authentication with user 
and password but I can't make it work. 
In the identity configuration of kphone I have set "jorge" in "user part of 
SIP URL" and "authentication username" and I have set "asterix" in "host part 
of SIP URL" and "outbound proxy"
The same configuration with user and password works fine with windows 
messenger 4.7

---------------------------------------------------------------------------------------------------------

The error messages I get from kphone are these:
