I know about it, but still have to make this work ( in order for that plugin
to work if i was to use it ). And i asked another questin :) (no heart
feelings). Sip will return via -N a nagios readable format, and that is all
about that plugin, returning 0 or 2 error codes. But i'm not eperienced with
SIP. I merged something like that with BigSister some time ago, it is easy.

Can somebody give me a real example (file included) that works ? the
SIPproxy will not try to auth, and i still do not know why. I've been
reading for the past 2 hours, but in vain. I guess i must mut some extra
parms in a _file_ and pass them via -f switch, but hell knows what sould i
write in there. :(.

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

the problem is : SIP/2.0 401 Unauthorized and Digest in the 402 response
above ???? i googled and find nothing cut crap. I read and ... u know, it's
easier to read the RFC in a couple of days than reading all that whatever
you want to call it about SIP. SIP and SDH/DWDM are poorely documended, and
everybody know this, i guess.(no need for links like
http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/Cookbook_D2/
and Co, i already read them). The problem is taht this program must be done
in about ... whow, 3 hours from now. And i still ain got a clue abou hou to
see if authentificates ok, the rest is done.

I must generate smth like :
Digest username="jan", realm="iptel.org",
  nonce="dcd98b7102dd2f0e8b11d0f600bfb0c093", uri="sip:iptel.org",
  qop=auth, nc=00000001, cnonce="0a4f113b",
  response="6629fae49393a05397450978507c4ef1", opaque=""
but i do not know how to do that with sipsak (generate a (forced ???) Digest
reponse).

Thank you in advance
