Have a NEAX 2400 IVS and using Zeacom. Have a dterm phone with message light flashing. I have read through the posts on this sight and have tried most everything but light keeps flashing and no messages in box. Have tried deleteing mailbox and putting back, left message deleted message, *9, *33 and no luck. Any other suggestions would be greatly appreciated. Nortel and Avaya guy here but recently thrown into NEC world.
