When I see your log above, the error part is begin with this line.
2009-04-15 18:24:44 [9679] [6] ERROR: AT2[itegno]: Couldn’t connect
I believe this is error when connecting to your cellphone device. Please re-check your kannel.conf file, especially this line.
device = /dev/ttyUSB0
modemtype = auto
Note:
ttyUSB0 is your modem connection type.
Confused ? use #dmesg for more information.
First, disconnect your modem connection cable (DKU-5) from your PC. Then from Unix terminal, type : # dmesg
At the last line, you will see that the cable is unplugged.
Plug the cable to USB, and see again on # dmesg
You will see what USB was used for the connection.

***the italic part is always looping*
*then I start the *smsbox /etc/kannel.conf*

the result is as follows:

everything sounds OK , except for the bearerbox error and warning.
I tried to send an sms by hitting this URL:

*
http://localhost:13013/cgi-bin/sendsms?username=playsms&password=aaaaa&to=+62818095*****&text=test&from=test
**
*and the page result *3: Queued for later delivery*

after I checked the smsbox, it displayed:

I guess the smsbox waits for bearebox to connect to SMSC successfully, but
the bearerbox still cannot connect.
*2009-04-15 18:24:44 [9679] [6] ERROR: AT2[itegno]: Couldn’t connect
(retrying in 10 seconds).*

does anyone have solution about this issue??

thank you

group = sms-service
keyword-regex= .*
catch-all = yes
max-messages = 1
get-url = “http://domainnameyahoo.info/sms/sms.php?phone=%p&text=%a”

then, you create sms.php file within sms directory.
# cat sms.php
< ?php
extract($_GET);
// phone=%p&text=%a"
// echo "telp :".$phone." ";
// echo "text :".$text;
//-------------------------
// Write your own log method here, you may use mysql or text file database.
//----------------------------
$info = " Sent from domainnameyahoo.info";
if ( $phone!="" || $text != "" ){
if (trim(strtolower($text)) == "status" ){
// check server status
}
echo $info;
}
// all echo syntax will be reply-to sender
?>

I hope that will help.
