Hi,
1) To push SMS you will need:
Application -> Kannel -> GSM modem
-or-
Application -> Kannel -> SMSc link
Application is some kind of web interface to facilitate and schedule pushes.
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.

Nikos

Subject: Two Basic Questions, Please?
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
