Hello, Are you using DLR ? Are you using sim buffering ?
There is two others things to consider : 1/ the capacity of a modem to send thousand of sms => if it send, it got less time to receive 2/ capacity of the network to make retry to your phone => some network does not make several retry when then send feedback to reduce the "noise" and lower their smsc licence. So one of the solution is to have more modems, it will "load balance" the eak and you will have a better quality of service.

I use kannel mainly to send SMS and not really as a SMS services system. Anyway I'd like to be able to use services now. The fact is that I send thousands of SMS a day and receive hundreds. The problem is that almost all received messages are stored into mobile phone and not routed to kannel. The config is the following : group = modems id = siemens_sl45 name = "Siemens SL45" detect-string = "SIEMENS" detect-string2 = "SL45" init-string = "AT+CNMI=1,2,2,2,1" keepalive-cmd = "AT+CBC;+CSQ" speed = 19200 enable-hwhs = "AT\\Q3" need-sleep = true Appears that this config is ok as when I launch kannel everything is ok and received messages are correctly routed to kannel. The problem comes when launched on production. When the "flow" of messages to send arrives - messages are no more handled correctly and stored in Phone SIM. For exemple : during a day session 10000 SMS sent and only 15 received in kannel (200 SMS in phone) I had a look in logs but I saw no errors - It seems like AT+CNMI is back to 0 and no more route messages to kannel. I saw some AT + CNMA sometimes that I suppose is the reason but what can I do ? Thanks for your help. Regards, LoLoVioLo
