Hi Nikos, Many thanks for your repsonse. It is really useful. Before actually sending my enquiry to this list, I had done some searchig for a while on google, and I understood that the only way to send sms message to recepints is by going through an SMS Centre for the dsetination network. In your reply, you mentioned as an option: Application -> Kannel -> GSM modem Can it really be done that way - *bypassing* the SMS centre? And if yes, what is considered as "low volume"? Would 1000 messages per day be 'OK' with a sim card provider?
And of course, it all depends on the destination network. Real SS7 connections may not be an option. I would appreciate your advice.

Optionally you can substitute one of kannel's components, smsbox, with SQLbox for sending bulk. GSM modem provides for a low volume, cheaper usually interface using a SIM card. But volume is restricted else SIM maybe disabled. SMSc provides for a more reliable interface, however, throughput is restricted according to your contract. Volume is unlimited (of course you are charged for each SMS). You can also shop around to get the lowest price globally, whereas with a SIM you are restricted by what your operator gives you. 2) Cost depends on your volume and destination. If Clickatell is an aggeragator, ie routes SMS to other SMScs, you can do better than them. If, however, they have real SS7 connections, given their volume, it is unlikely.

Hello, I have windows xp on my pc, and am very interested in Kannel. Before installing Linux and going through the whole process, I would like to know, if possible, please:- 1. To send sms messages, what else would one need apart from:- Kannel + GSM modem + SMSC connectivity (for recepients' network) Anything else apart from the above 3 'components'? 2. Would that arrangement be actually cheaper than to go through some bulk SMS suppliers like Clickatell, for example? I think it should, but I am not sure. I would greatly appreciate an answer. Best regards, David
