asterisk users - Dec 2005 - RE: how to make contribution in asterisk

hi all,
 
              I am a newbie in asterisk. I am doing my project on implementing
"VoIP gateway".I installed asterisk 1.0.7 on Debian. This package was
available in Debian-Sarge.
 For this implementation i choose asterisk.I just bought digitnetworks X100P
PSTN card. I have some queries :
 
 1)For this project purpose, Is this card suitable and enough? i m just going to
download 3-4 soft IP phones. Since this card has only one FXO port, I think with
this i can get PSTN call on my soft IP phones and also i can make call from any
soft IP phones to analog phone. whether i m thiking in right direction or not?
 
 2) After installation of this card i will go for simple dialplan structure to
confirm how this VoIP gateway works.Since i m new to asterisk, By doing this i
will get better idea abt asterisk. Am i doing right?
 
 3) Since i m doing my project work, i have to show some implementation which
should be my own. I heard about Asterisk Gateway Interface (AGI). So  by using 
AGI what can i develop?
 since it uses PERL,PYTHON,PHP for development, which shd i go for. As all three
are new for me. Which will be fast and easy to learn?
 
 4)I think other option available for me is to do some modifications in the
source code? How much time it  will require to analyse and understand the
asterisk code? I m not so much comfortable with C programming. So whether it
will be be suitable to go for this modification? how much time will be reuired
to understand the code? (probable time in days). Or i shd go for AGI?
 
 5) Are there some other options available with which i can show that i have
worked with asterisk and developed something new, so that i can showit as my
project work?
 
 suggestions frm all asterisk users are most welcome...........
 
 thanks

Compile and install 1.2.1, it's a bit different (in a better way, of 
course) and there's no sense in learning something that will change soon.

Yes, if you want to assign a different number to every softphone and 
have the external dialer select the phone with a number placed after the 
did be warned that the call will be answered even in the softphone 
isn't, so the caller will pay just to wait for you to answer. (not sure 
on this, maybe there's a solution)

I usually go with : sip registration, registered sip calling Echo app 
(most useful to test nat issues), internal softphones calling each 
others, registered sip calling outside (to a cell, so I can look at the 
given did),  outside call routed to an internal sip phone.

Python, and learn a bit of object oriented programming too, it will come 
in hand if the project becomes complex

Go for AGI.

Actually I miss the exact meaning of "project work", are you a student
and is something like a pratical exam ? Are you totally free in what 
functionalities to implement ?
