Thanks all for the feedback. It never occurred to me to utilize a SMDI port or Amish's software solution. Both good idea's I plan to pursue. Thanks again.

Your phone recognises that this is a MWI SMS and sets/clears the icon accordingly. To implement this function download a copy of kannel. Connect kannel to your SMSC via SMPP. When a voicemail is deposited, send an SMS via kannel with the MWI set to the users phone. Your can send another SMS later to clear the MWI icon when the user accesses their voicemail. For more info search for "mwi" in the kannel 1.5.0 userguide. Enjoy, A.

Asterisk voice mail was also implemented but soon realized the MWI feature was not functional to GSM handsets, everything else works great. VM-MWI works on soft phones just fine. Has anybody successfully made this work to wireless handasets? We're happy with the performance of our system, maybe we're asking to much. On a working platform a GSM MAP message transaction via E.164 (GMSC to SMSC) is utilized. Any Feedback appreciated Dale -------------- next part -------------- An HTML attachment was scrubbed...
