I am the system operator. I need the calls made to "0" to rollover to another extension if I do not answer. Then if she doesn't answer, the call needs to go to my operator voice mail. I had this set up previously, but it somehow was wiped out. I do not want these calls to effect calls direct to my extension or to the call queue I am also a part of. Is there a way to set this up without effecting all my calls? I tried advanced settings with no luck.
