i have a DN on key 13 on a phone. I built a dummy 500 port with the same DN and had this 500 port hunt/fna to voicemail. My question is, do i need to make the dummy 500 port's class of service MWA? the phone that it appears on has MWA but I'm not sure if I need to do it for the dummy 500 port. If I make it MWA is that going to confuse the voicemail as far as where to put the light on since the dummy port doesn't actually exist? thanks.
