asterisk users - Jun 2010 - calling machine over sip

Actually my problem is not related to sip.conf and extensions.conf. I have
used only standard files from martin pdf which are given as example.
I am able to call some system connected over LAN, when each has a softphone
and are registered on a asterisk server. But now what i want is instead of
using the softphone I write a function in my file which will be executed
when the call is placed.
In that file i wrote
   $agi=new AGI();
   $agi->exec_dial(SIP,2002,NULL,
NULL,NULL);
I have used the exec_dial function found in phpagi.php . It is built above
basic dial function. Here 'agi' is an instance of class AGI, which has a
method exec_dial.

When i execute the php file, over command line on my unix machine, I am
expecting a call on the softphone which I have registered on the asterisk
server.

For ip clarification:
all have static ip:
server ip:172.26.48.208:5060
i have configured twinkle as a softphone client on 172.26.48.113:5061, since
on the asterisk server cli when i use 'sip debug set peer 2002' it shows
the
registered ip, as i said earlier, but again on 'sip show registry' no
value
is displayed. I don't know what's going on.
  In the softphone I give domin information as the ip of the asterisk server
i.e. 172.26.48.208. In the softphone it shows registration successful.

Thanks in advance

Something on voip-info.org (sorry, no URL handy) says dialing from an AGI 
is not recommended because you lose control of the call within your AGI -- 
execution continues at the statement in your dialplan after "agi()." I
can't "vouch" for the accuracy or applicability to your version of
Asterisk. I would code up my AGI to set a channel variable and then dial() 
in the dialplan.

When you execute an AGI from a shell command line, it is not talking to 
Asterisk. The AGI protocol is based on STDIN and STDOUT. When executed 
within Asterisk, STDIN and STDOUT are "piped" to Asterisk. When
executed
from a shell command line, STDIN and STDOUT is your TTY. All your AGI is 
doing is printing "pretty strings" on your screen and waiting for you
to
press return. (Personally, I would consider it a flaw in your AGI library 
that it doesn't complain about the invalid "response.")

If you execute your AGI using the agi() application in your dialplan and 
you have enabled agi debugging, you will see the "conversation" of 
requests and responses between Asterisk and your AGI. Usually you will 
also see what you are doing wrong -- an unexpected "echo" or
"print" that
violates the AGI protocol, a syntax error, etc.
