Hi,
Yes, a GSM modem (or a bank of those) are fully supported by kannel. I have no
clue what is the volume restriction, it depends solely on your operator. I just
use dedicated SMSc links, but some other guys in the list have more experience
with it. Bear in mind that in both cases the final step is an SMSc. The only
difference is that with a GSM modem, the SMSc is your provider's responsibility.

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.
Best regards
David

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

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
