Hi Bogdan,

sorry for delay... I think I found the reason why my dialogs didn't get cleared 
correctly.

I had issues with some SIP phones including proxy auth. credentials in loose 
routed ACK and BYE messages (see "Contents of ACK in up-to-date RFC3261", 
http://lists.opensips.org/pipermail/users/2009-January/002639.html).

Because I wanted to remove the credentials for upstream and avoid the annoying 
error message "ERROR:auth:consume_credentials: no authorized credentials found 
(error in scripts)", I included the following code snippet in my outbound route 
around the "consume_credentials()" function:

if (is_present_hf("Proxy-Authorization")) {
        if (loose_route() && is_method("ACK|BYE")) {
                remove_hf("Proxy-Authorization");
        } else {
                consume_credentials();
        }
}

After commenting out my additions, the "ERROR:auth:consume_credentials: no 
authorized credentials found (error in scripts)" message reappeared, but all 
dialogs get cleared correctly and the error message from the dialog module 
disappeared. Maybe the "remove_hf()" function is the problem here?


Regards,
Robert

Hi Robert,

Please post the dialog module parameters and the SIP trace for the call 
with x-lite - I will check if xlite does something wrong in the 
signalling. Also please attach the full debug log (debug=6) from 
opensips (for the call).

Thanks and regards,
Bogdan
