ok...
I obtained the correct password and was able to administer the system. But I am still unable to get internal or external calls to forward to Vmail at all. Current set up is as follows...
770 = calling group (auto log in) phone extensions 10, 11,12,13,14,15,16,17,18,19 and 20
771 = Calling group for vmail ports/ext 34,35,36,37 Integ vmail
772 = Calling group for DLC ext 38 39 40 ( I don't know why these are the ext's but I am unable to change them) Integ Vms
I set up the ext to be covered (10-20) in cover grp 30 and set up 771 with all of the ext 34-37 that make up the vmail module.
I then went through the manual and followed the steps for setting this up starting with heading "Programming the Communications System" thru page 152. I still receive a busy when I dial a busied out ext and the phone just rings when not busy from both internal and external calls.
