Brand new 7100 V 4.95

Call into Day or Night or Holiday Menu
Dial Ext e.g. 205
VM says transferring to Ext 205, which it is.
Ext rings, no answer
Goes to VM Day Menu instead of MBX
Happens on all ext

All menus and mode settings seem correct
For the life of me, I can't see where anything is mis-programmed

Help ?
