When testing, we can leave a voice mail, the MWI is instantly lit, and we get an email with the voicemail as an attachment. We then open the attachment, listen to the voice mail, then delete the message in outlook. The mwi is still lit on the phone and the voicemail is still available on the phone itself.
We have tried cached mode and online mode. Outlook 2010 and 2013. With and without the NuPoint plugin.
We are using MATAI for MWI and IMAP for connection to exchange.
What do we need to check to get this working.
