We have a project going for one of our big companies. They are mostly a Nortel shop so we have M3904s with the add on full duplex speakerphone kit. We have some sites in the UK and Nigeria that have Mitel systems. Both of the users that they want to have full duplex at there desk station have superset 4025s and 4150s. Does Mitel have a digital set that is Full Duplex? Or any adapters such as the Nortel add on kit? I have looked at the Mitel 5312 IP set and it looks to be a full duplex unit. Any have any thoughts or opinions about this unit or other suggestions on a possible solution?

Two girls later and I'm back.....lol...been gone a while but see same faces still here. Lol
