This is interesting because I am doing a very similar thing. I have four
Cisco phone, two 7940 and two 7905 and a couple of ata186. An incoming
call rings all six phones. There is a single voicemail box that is
assicate with every phone. The MWI indicator lights up on all phones when
a message is received. It also extiguishes from all phones if the
voicemail is deleted from any phone.
