The algorithm seems to be correct, check the contents of subscriber
table to make sure that you have username admin with realm iptel.org and
password heslo there.
Also make sure that you have calculate_ha1 parameter uncommented in the
configuration file of SER. If you do not use the parameter then ser will
use ha1 column instead, that column contains MD5(A1) and that string may
be built using different realm (common source of problems). If unsure
use calculate_ha1 parameter.

Hi all,
I'm trying to implement the MD5 digest authentication in my SIP client to
register with SER, and I sent and receive:
REGISTER sip:10.0.0.113:6060 SIP/2.0

Following RFC 2617,
A1 = admin:iptel.org:heslo
(where SER's default username:password pair "admin:heslo" are used, with
realm="iptel.org)
A2 = REGISTER:sip:10.0.0.113:6060
(where method="REGISTER" and digest-url="sip:10.0.0.113:6060" which
agrees
with request URI, and note that SER is running at 10.0.0.113, port = 6060)
Response was calculated as
MD5( MD5(A1):nonce:MD5(A2) )
And my new REGISTER msg is:

But I still get another 401 Unauthorized response ...
I'm pretty sure my A1 is correct. Could it be my A2 where method shouldn't
be REGISTER? Or may be the digest-uri is wrong?
Thank you in advance.
