[Serusers] Newbie : SER and sipsak

[Dragos CHIRIAC]

Hello,

I must do a monitoring tool for a SER sip proxy. I have a user and a pass to
it. I can make calls with the combination.

Tests I-ve ran:
rhemaxos root # sipsak -n -s sip:me at myhost:5060 -v
SIP/2.0 200 OK
Via: SIP/2.0/UDP 127.0.0.1:1675;rport=
From: <sip:sipsak at 127.0.0.1:1675>;tag=2fbba8ac
To: <sip:**************:5060>
CSeq: 1 OPTIONS
Call-ID: 800827564 at 127.0.0.1
Content-Length: 0

All seem ok

but if i run:

rhemaxos root # sipsak -I -U -n -s sip:me at myhost:5060 -v -a mypass

i get smth like:

Call-ID: 2105779733 at 127.0.0.1
WWW-Authenticate: DIGEST realm="whatever.com",
nonce="fde24b2e80f3f1c96ec8e962d34627d0", algorithm=MD5, opaque="3251298552"
Content-Length: 0

error: couldn't find authentication method Digest in the 402 response above

The dumps (i use nast) from Xlite look a lot different.

Well, really beats me, i'm new to voip, and i really need help with this
one. It does not even try to AUTH me.
I know that is my fault, but i need some help with this one. I would not
like to read the SIP RFC just to monitor a SIP proxy. I have basic to medium
theoretical knowledge of the protocols and no experience in the wild.

Thank you in advance

Dragos
