<tt>Hello Rik,<br>
<br>
It may be silly , but are you sure you filled in the proper
credentials (realm, auth user and password) ??<br>
<br>
Also, based on how the response for digest is computed, you can
double check the OpenSIPS auth response (calculating the HA and
md5 sums as per RFC 2617).<br>
<br>
Regards,<br>
