Thank you Anton for your help and this sample.
So I’ll continue my tests to find out how to make it work.
I have just few last questions before we close this thread:
What’s the recommended GSM Gateway to use with PlaySMS ? I used SMStools recently because Gammu was not compatible with my modem, I still can change it if it doesn’t work well in my context.
Also, how can I handle an external web API call everytime I got an incoming SMS (and also a delivery status) ? I want to tranfert all the incoming messages (and delivery status) to an other server, I know I can make a php plugin, but maybe there is an other way ?
