Has anyone gotten the voltage based MWI lamps on an Aastra (formerly Nortel) M8314 analog set? We have a large customer site where we replaced a Nortel Opt. 61C PBX with a new Mitel 3300 Mxe and have not been able to get any of the customer's 8314 set MWI lamps to light. I have already checked the analog ONS / OPS circuit descriptors and Class of Service Options to make sure that they are correct. Any ideas?
 
what is the min voltage to light the msg waiting on the phones? ASU II works at 90v for MSG waiting.
 
So we can assume the MWI works on other analog sets but doesn't on the Aastra?

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.
 
Bobcheese, It's supposed to be 90Vac to trigger the light but it's not working. The light does flash, however, in synchronizaqtion with rining voltage being applied.

LoopyLou, It works with a generic (Cortelco, I believe) 2500 set with a message waiting lamp and an Aastra 9316, but not with an Aastra 8004 or 8413. These are the sets we tested with so far.
