401 Unauthorized is a challenge sent by a sip proxy.

You are supposed to handle that challenge and send back an other REGISTER or INVITE request which contains the following field:

Authorization: Digest username="toto", realm="toto.com", nonce="fsdg324fdsfg34bfd",...

Where username is your login and nonce generated from your password and parts of 401 message

Check your login and password configuration or check if that user exists on your SER server

Paul

Objet : [Serusers] Cisco 7960 don't REGISTER

Hi,

I'm trying to get my Cisco 7960 working with my SIP server running

SER-0.9.0, but it never registers in the server. When I run "ngrep sip"

I always get "401 Unauthorized" responses sent from server to phone. I

don't understand why is it happening because I think it's everything

well configured. What could be causing this problem?

Regards,

Ricardo.
