press sp-phone enter *71029,
then enter the outside number, then #, you will hear a tone that means call
forwarding is activated.
to cancel press sp-phone *7100#
or simply dial 790 for extension data clear
should you dial 9 or another access code for outside calls?
If if you dial an "outside" number on an intercom line it will look at the first 2-3 digits as another extension. You need to dial the Central Office access code, or use a line key assigned to an outside line.
You need to know what extension is causing the forward directly to voice mail. Chances are that this extension has ringing lines programmed to it and the forward on busy is to voice mail. ANY PHONE THAT HAS RINGING LINES SHOULD NOT BE SET TO FORWARD ON BUSY. If they happen to be on the phone when a call comes in it will go straight to their personal mailbox.
With one CO line you can only make or receive one external call at a time. You can have extensions connected on intercom calls, but once your CO line is in use, anyone calling in will get a busy signal, as will anyone in the office trying to make an outside call. You'll need additional CO lines if you want to have several outside calls going on at once.
Unfortunately if the receptionist is using priority call (f69) there's not much you can do. Priority call is an administrator programmed function that overrides when your on a call and when the set is in do not disturb. Maybe bribing the receptionist might be in order.
If the person you are trying to reach is speaking to another internal extension, none of the outside lines will show in use. If their phone is not Call-Forwarded to any other extension (i.e. second extension or VM), you will get a busy.
