Where can I get a starting point for setting up sms via VoIP and via web.
I want to send SMS from VoIP or web to VoIP phones and GSM phones.
1. how to set-up?
2. which smsc should I use? (what is the price?)
3. which phones can be used?
Some telcos support sending SMS down phone lines, it's reasonably common
in Europe and there's an ETSI spec for it.
However it's probably easier to use something like Kannel which has an
http interface and then either connect that to an SMSC or locally
through a GSM terminal (phone).
SMSC connections and pricing will vary depending on what country you're
in. As a small customer (in the UK at least) it's unlikely you'd get an
connection to an operator's SMSC and you'd have to go through an
aggregator.
Best I got (in the UK) was 3p a text when I looked nearly 2 years ago.
This was to an outfit in Scotland - you connect via an internet enabled
API (ie. a bit of PHP code) and send the text via their service centre (or
texts - I was looking at 2-4000 a month, but they went up to half a
million a month).
What I do these days is use a Siemens GSM modem - with a SIM card in it on
a PAYG tarrif (my needs are minimal right now) Linux supports sending SMS
messages via getsms and putsms (which works in the pager section of
voicemail.conf)
Sending TXT messages to a VoIP phone is going to be challenging, I
think, but I'd like to think it is (or might be) possible!
