I am using windows xp and into that I am using red5phone sip_47 with red5 
server 0.8. I configured all thing properly when I type 
http://localhost:5080/sip so it's working perfect then I changed red5 property 
and change localhost and used my IP address. that also working fine.

At end when I run my sipphone so my login is done and it show me connection 
success and show me phone window. 
But at end in red5 console it show me an error given below.

RegisterAgent: onTransFailureResponse start:
RegisterAgent: Registration failure: 403 Forbidden (Bad auth)
