Hola Alberto:
Maybe your transmitter disconnects and that is why Kannel cannot
send any more SMPP packets to your SMSC.
- Did you check if both transmitter and receiver are connected?
- Try to send some SMS to a phone as a keep-alive before the 6 minute
period, and see if the problem persists. (Some SMSCs behave strangely
and disconnect the ESME if they don´t get an SMS, even if you send
enquire links...). In this particular case, you should disconnect and
reconnect :(
I hope this may be of help.
Rodrigo.
