asterisk users - Mar 2005 - CNAM for Asterisk

I am working for Accudata Technologies.  We
provide CNAM via http request or raw TCP/IP connection.
We would like to provide the same capability to Asterisk.  I installed
Asterisk on Fedora 2.0
and did reading about AGI and AGI application at
http://www.voip-info.org/tiki-index.php?page=Asterisk+AGI,
http://www.voip-info.org/wiki-Asterisk+Manager+API, and The Asterisk
Handbook Version2
but still not clear on how to interface a new application to Asterisk.

At first I would like to interface a simple client application in C that
connects to an IP and
Port number.   The application receives a phone number from Asterisk (???),
connects to our server, sends the phone number, receives a caller name from
the server, sends the name to Asterisk (???).

Thank you for your help.

What you need to do is create a small resource module (res_accudata 
would be a good name), and have that module register a dialplan function 
using the new function system just recently posted in Mantis and 
committed to CVS.

If the module will require configuration (for example, to specify the 
server to query, or username/password for authentication), then it can 
read a config file named accudata.conf for that info (you will have to 
define the format, but I'd suggest just putting variables into the 
[general] section).

Finally, your function can accept a single parameter (10-digit NANPA 
number) and return a string. Usage would be something like:

   exten => 5000,1,SetCIDName($(accudata_CNAM 6025551212))

There is no need for an external daemon; the res_accudata module can 
open a socket to your server and send/receive data like any other C 
program would do.

If you need help doing this, join the #asterisk-dev IRC channel, or if 
you don't have the skills to do it, ask to have one of the Asterisk 
development team members do it for you (but expect to either have to 
wait until they have time, or to offer a bounty as an incentive <G>).
