I maintain 2 separate Octel servers. A 250 with software release 3.1 and a 350 with the same release. Menu 13.5 allows me to turn message waiting indicators on with no problem on the 350, but on the 250 I get a prompt that says mwi must be turned off. I can get no further that that. Is there a way I cvan eitther get around that or manually turn the mwi's off??
