[Sipsak] SIP/2.0 404 Not Found

[Raj Adhikari]

Hi group,
I am using Asterisk 1.4.9.
My intention is to monitor asterisk server. So I used sipsak. I have 
registered an extension 999 with password 999 at the asterisk server. 
But using sipsak I am getting SIP/2.0 404 Not Found for this or any sip 
user. Why SIP is not sending 200 OK response for simple SIP command with 
valid extension? I am novice in SIP. But I am not getting expected 
result from sipsak. May be you can look at the following two examples to 
see the problem. I would like to get SIP 200 OK when sending simple 
INVITE command. I will appreciate if you can enlighten me if I lack 
knowledge on SIP.

Here is the sipsak traceroute:

----------------------------------------------------------
Even if I provide password with -a 999, I am getting the same result.  
But look when I issue following command I get the 200 OK response.
