I for example sent 20 000 SMS. After that I gradually start to get the delivery status. After some time, the delivery status stop coming (after about 15,000 statuses). Then I pull out SIM card, put it into the phone, and the phone starts to inform me about the status that a particular room has received or not received SMS. Why kannel suspends receiving the status when I use gsm modem?
Thank you very much for your answers.
