Yes, that´s the way, kannel connects to SMPP servers, and playSMS talks to Kannel. One piece at a time. First, be sure that kannel is connected to SMPP, and you can send messages through it (kannel http api). Then, configure kannel´s playSMS plugin, create a SMSC and so on. Isn´t trivial, but works very well.
thank you for your reply.
But after I added smpp with Kannel’s http api add-smpp, the service could not be started when the service was restarted. It may be that there is a problem with my parameters.
Excuse me, how to use this API.
