I hooked up my new Grandstream today and called to leave myself a voicemail from my cell phone. The MWI blinked the light on my panasonic, which is great. I checked the voicemail and used 7 to delete it, but as of about 15 minutes now the MWI is still stuck on. I just listened to the message, pressed 7 to delete, and hung up. I would think this would clear the MWI but it has not.
