After some testing, I have found Kannel one of the best , fastest SMS and WAP gateway among other open source sms gateways , capable of handling several hundreds of requests per second.
Following is a guide on how you can configure your own Local SMS HTTP gateway using KANNEL
(The aim of configuring kannel on my Ubuntu box was that I required it to send sms via DMASOFTLAB RADIUS MANAGER which uses API to send sms via clickatell HTTP gateway for New Account / Expiry Warning / Password recovery via sms , verification code and many other cool functions. It comes with the clickatell HTTP gateway API which off course require you to buy sms bundle package and do require handsome amount of $$ if you have a huge number of users, Therefore to save $$ money , I created my own gateway)
O/S = Ubuntu 10.4
Hardware = Teltonika ModemUSB/E12 UM1400
First install KANNEL using apt-get (the easiest one 
)
apt-get install libxml2
apt-get install kannel
NOTE:
Kannel works great with the Linux base distribution BUT there are some workarounds to make it run on Windows. Do some googling and you will find few links for it.
Now open the kannel config file by
nano /etc/kannel/kannel.conf
Remove all the lines and paste the following config
# Syed Jahanzaib # http://aacable.wordpress.com # aacable [at] hotmail.com group = core admin-port = 13000 smsbox-port = 13001 admin-password = zaibadmin status-password = zaibstatus log-file = "/var/log/kannel/bearerbox.log" log-level = 0 box-deny-ip = "*.*.*.*" box-allow-ip = "127.0.0.1" group = smsc smsc = at modemtype = teltonika device = /dev/ttyACM0 # change this to match your port, it could ACM1 , if you dont set it correctly, it will not work and you will get error in logs that unable to connect to device) speed = 19200 my-number = 0333302100000 # (put your sim number, not necessary) group = modems id = teltonika name = "Teltonika E12" detect-string = "Undefined" enable-mms = true init-string = "AT+CNMI=2,2,0,1,1" speed = 115200 group = smsbox bearerbox-host = localhost sendsms-port = 13013 global-sender = 13013 sendsms-chars = "0123456789 +-" log-file = "/var/log/kannel/smsbox.log" log-level = 0 access-log = "/var/log/kannel/access.log" group = sendsms-user username = kannel password = kannel concatenation = true max-messages = 3 group = sms-service keyword = default get-url = "http://localhost/kannel/receivesms.php?sender=%p&text=%b" accept-x-kannel-headers = true max-messages = 3 concatenation = true catch-all = true
Open two terminal windows and issue below commands in each terminal box in the following order.
1. Start the BearerBox
bearerbox -v 0 /etc/kannel/kannel.conf
You may see the following screenshot if your config is ok
Now leave it running.
2. Start the SMSBox (in second terminal window and leave it running as it will show you the debug logs)
smsbox -v 0 /etc/kannel/kannel.conf
You may see the following screenshot if your config is ok
[If you receive error that the address is already in use, first issue the command service kannel stop]
.
Now From your browse, type the following to make sure kannel is working fine 
http://101.11.11.250:13000/status?password=zaibstatus
[change the ip and password to match your config]
and you may see the following screen , if your config is ok

Howto send SMS via http command
Open your browser and paste the following command.
http://101.11.11.250:13013/cgi-bin/sendsms?username=kannel&password=kannel&to=03333021909&text=ZAIB+KANNEL+WORK
Change the IP / ID + Password = and number to match your local configuration.
The result would be similar to the following . . .
