asterisk users - Jun 2008 - Controlling cell phone VM / Fax waiting notification icon for asterisk VM

I little more digging and I confirmed that cell phone VM and FAX waiting
icons are in fact controlled by a proprietary SMS message format.  Here's
what I found:

 

 

Message Waiting Indication Group: Store Message 
This Group allows an indication to be provided to the user about the status
of types of 
message waiting on systems connected to the GSM PLMN. The mobile may present
this 
indication as an icon on the screen, or other MMI indication. The mobile may
take note of 
the Origination Address for messages in this group and group 1100. For each
indication 
supported, the mobile may provide storage for the Origination Address which
is to control 
the mobile indicator. 
Text included in the user data is coded in the Default Alphabet. 
Where a message is received with bits 7..4 set to 1101, the mobile shall
store the text of 
the SMS message in addition to setting the indication. 
Bits 3 indicates Indication Sense: 
Bit 3 
0 Set Indication Inactive 
1 Set Indication Active 
Bit 2 is reserved, and set to 0 
Bit 1 Bit 0 Indication Type: 
0 0 Voicemail Message Waiting 
0 1 Fax Message Waiting 
1 0 Electronic Mail Message Waiting 
1 1 Other Message Waiting* 
* Mobile manufacturers may implement the "Other Message Waiting"
indication
as an 
additional indication without specifying the meaning. The meaning of this
indication is 
intended to be standardized in the future, so Operators should not make use
of this 
indication until the standard for this indication is finalized.

 

 

Now the tough part...does anyone want to create an app to send notification
to a cell phone to set/clear these bits?

could you provide a link to where you got the info from?  I'd be interested
in
seeing if i can get this to do anything useful.

Yes; this is the same sticking point I hit; you can't use an SMS email 
gateway, because the SMSC mangles the message format in order to prevent this 
and other hacks.  (Imagine anyone sending you an email and controlling this 
and other things on your phone!)  Your best bet is to try and find an 
internet SMS company that can control the MWI for your provider.

Hi,

you can set these flags with a GSM-Phone connected to gnokii/gammu, or you can
use a commercial SMS-Service like http://www.truesenses.com, both can be called
via an externnotify script.

On the downside, asterisk does not yet have a mechanism to track the status of
an external MWI, so you have to do this yourself (send an SMS when you have new
messages and clear the MWI after you've listened to the last one...)
