MWI

Hello,

I have a questions about MWI.

I'm not using tribox just asterisk with aastra XML script (with some adaptation) and when I remove a voicemail message with aastra xml script , the MWI is not updated.
if I do it with the usual way (with I IVR and the voicemail application all is ok).

I see that the xml script remove directly in the file system the wav file so I need to know how to indicate to asterisk that this file is deleted and that he need to refresh the MWI of the phone.

Regards

Laurent
