The "WWW-Authenticate: Digest" indicates that the Cisco router's authentication header is not correctly formatted or does not have the right information for registration. The config on the registrar is good information, but can you post the registration information from the Cisco router? The problem is likely there.

I made some modifications and I took 200OK in registration request. I took also replies on INVITE messages.

I will post some informations when I 'll be available. Now, I must set the dial peers for incoming and outgoing calls.

Thanks for your help...
