<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Bogdan.<br>
<br>
For our particular need, it looks like we need to send the response in a more
complex way:<br>
<br>
response = md5(HA1:nonce:nonceCount:clientNonce:qop:ha2)<br>
<br>
Could you give us any hint about nonceCount and clientNonce parameters? Documentation
is not very clear.<br>
<br>
Thanks and regards.<br>
<br>
Sergio.<o:p></o:p></p>

<p class=MsoNormal>Hi Matti,<br>
<br>
Actually it is SIP auth, so digest auth (RFC 2617)<br>
Shortly:<br>
HA1=MD5( auth_usernam ":" realm ":" passwd )<br>
<br>
HA2=MD5( method ":" ruri )<br>
<br>
response=MD5( HA1 ":" nonce ":" HA2)<o:p></o:p></p>
