Feature Reference
5-184 
■ Users can ring any of the seven Hunt Groups or voice signal Hunt Groups 
1–6. For more information, see Group Hunting—Ring/Voice Signal.
■ If Station Lock is used at an extension, users cannot dial outside numbers 
except Marked System Speed Dial Numbers and numbers on the 
Emergency Phone Number List (#406).
■ If dialing restrictions are programmed for an extension, the system may 
prevent a user at that extension from placing certain calls. For example, a 
user may not be allowed to dial 900 numbers from the extension. (Or an 
extension may be programmed to take incoming calls only, so the user 
cannot dial out at all.) The following features provide dialing restrictions: 
Disallowed Phone Number Lists (#404), Line Access Restriction 
(#302) Pool Access Restriction (#315), and Outgoing Call Restriction 
(#401).
■ The following features can be used to override dialing restrictions: Allowed 
Phone Number Lists (#407), Emergency Phone Number List (#406), 
Marked System Speed Dial Numbers, and System Password (#403).
■ Users with system phones can enter account codes to track incoming and 
outgoing calls. For more information, see Account Code Entry. You also 
can use Forced Account Code Entry (#307) to identify extensions that 
must enter account codes prior to dialing outside phone numbers (including 
those on the Emergency Phone Number List).
■ Users can signal, then speak to, system phone users who are already 
active on a call to alert them of important business matters, provided Voice 
Interrupt On Busy (#312) is Assigned for the recipient.
Considerations
The following instructions assume that system phones are set (using Automatic 
Line Selection) to automatically select outside lines first, and standard phones are 
set to select intercom first. This means that when a user with a system phone lifts 
the handset, the user hears outside dial tone (if an outside line is available); but 
when a user with a standard phone lifts the handset, the user hears intercom dial 
tone.
How to Make an Outside Call 
System Phone
1. Lift the handset or press S.
The green light next to a line or pool button is on steady and you hear the 
outside dial tone.
2. Dial the phone number.
On a system display phone, the dialed number appears on the display.
If you are using a PBX or Centrex line, you also may need to use a dial-out 
code (usually 9) before you dial a number outside the system.
