Well, I realize that there must be some proprietary protocol between the
carrier and the phone, since they have a dedicate spot on the cell screen
for # VM waiting...
As for an SMS message, is there a module/app which allows easy SMS
messaging? (I looked a couple of years ago but only found commercial
modules)
Don't quote me on this, but I think that the standard voicemail notifications
that cell phones recieve are just a regular SMS message but in some kind of
special format that the phone recognizes and does not display as a regular
text message.
I had an unlocked Moto razr at one point that didn't come from my cell
provider, at one point while I had it the VM notifications didn;t really
work... everytime i got a VM I'd get a SMS message with special characters in
the message body. I sort of chalked it up to not using the branded firmware
that my provider would have put on my phone if the phone had come from them.
At any rate, if I'm right, and you can find some information on that protocol,
it might turn out to be alot easier than you think.
and btw - Asterisk ships with app_sms but depending on your country it may not
really be what you are looking for. I could be very very wrong here, but I
don't believe Asterisk has a great implementation for text messaging in North
America. This is probably because every cell carrier seems to do it just a
little bit differently.
Depending on your needs however, most cell carriers offer email-to-SMS
gateways so you can just send an email to
<yourcellnumber>@<yourcellcarrier>.com kind of thing... if you need it to
work from a machine with no Internet access however, then you might need to
do something like use a dialup modem to dial into your cell carriers TAP
number (provided they offer one and you can either explain to the tier 1
support guy what you are looking for, or you can find the number on the
internet).
However again, I don;t believe Asterisk has any interface for TAP, but in
theory you could use something like the "sendpage" daemon to handle the TAP
stuff and then have Asterisk hand off the text messages to sendpage using a
simple bash script and the System() application... if Asterisk had an
implementation for SNPP then you could send your messages to sendpage that
way - also *some* cell providers even offer SNPP gateways over the internet,
but again good luck explaining to the tech what you want.
I've actually been toying with the idea of creating a res_snpp or something
for this purpose since I already use sendpage for our server
monitoring/alerting system to page me on my cell via dialup TAP (so my
monitoring server can still page me in the event of an internet outage).
Anyhow, sorry that message got a bit lengthy pretty fast!
Check out http://www.ihub.com which have lots of information regarding
SMS messages, you can also use their software as a trial for 60 days to
see it in action.
