Hello All,

I am trying registration for my sip client through SIPp (through Actual ADSL line the subscriber using sip clent box is able to make successful registration & call). For the same number when I am tring through SIPp for Registration I am getting the 401 response( That is ok, I got with actual sip client also). After receiving 401, when I am sending Register then IMS core (of ALU) is rejecting the REGISTER with 403 response. I am using MD5 algorithm.

This is purely authentication issue.

Kindly suggest any solution.
