I have a no616 at my office and i'am in need of a user's manual and installation and setup manual,and if any one can answer a few questions does the NO616 have the abilty to have a voice mail system added to it? One that if the person the receptionist is trying to get a hold of is on thier line she could transfer the the call to that person's voice mail? Also does the NO616 have the capabilty to take a incoming call to receptionist and transfer it to a mobile phone number of person the caller is trying reach
