Hi, Gents.

I usually hang out in the Mitel and NEC areas, but I find myself responsible for a Definity. I have a working knowledge of Definity -- used to do basic MACs in a voicemail lab environment, years ago -- but am not certified on it (I am certified on Mitel SX200 ICP and NEC 2400 and 2000).

This is in a hotel, and there are serial links for PMS integration (Softbrands/HIS) and call accounting.

Call accounting is up and working, receives SMDR and relays data to PMS. However, PMS does not consistently transmit name display data, and does not consistently reset phones. I am also getting reports of phantom voicemail lamps and/or call-forward (coverage) to voicemail is disappearing.

Any suggestions for things to check out and common solutions? Words of wisdom?
