I'm using Kannel as an SMS gateway to send and receive SMS messages. I have downloaded, installed, and configured Kannel according to the document guided. I can send an SMS by typing http://localhost:13013/cgi-bin/sendsms?username=tester&password=foobar&from="from number"&to="to number"&text=Testing in a browser. However, when I send an SMS from a phone to the gateway, I got the error ERROR: request failed.
I'm using Kannel 1.4.3 installed on Ubuntu 10.04 LTS. I use a wavecom modem whose model is WAVECOM FASTRACK type DUAL BRANCH MODEM connected to kannel via serial port.
Should you need further information, please let me know.
I'm really thankful for your help.

An SMS gateway can also be used to relay SMS messages from one GSM network to another, if the networks do not roam messages normally. Kannel works as an SMS gateway, talking with many different kind of SMS centers, and relaying the messages onward to content providers, as HTTP queries.
SMPP is considered the industry standard for sending SMS to Network providers and is our native protocol. The Short Message Peer-to-Peer (SMPP) is a protocol used by the telecommunications industry for exchanging SMS messages between Short Message Service Centers (SMSC) and/or External Short Messaging Entities (ESME).
I think u may have missing SMS-service configurations
# Test
group = sms-service
keyword = default
