I noticed something with my VVX 400 and just wanted to share with the community. Normally if my phone has MWI indicating voice mail status, if I reboot the phone it will loose its MWI status and will have to wait until a new voice mail comes in before lighting up again...this is ok and know the config to add that will have the phone subscribe for message-summary after a reboot.
However there are times when I rebooted the phone and it comes back up showing the MWI, when I check capture the phone didnt subscribe for message summary and didnt receive any notifys from SIP server.
now am wondering if the Polycom internal memory stores mwi status at times?
