Central Office Calls, Placing


The system provides flexibility in the way each extension user can place outgoing calls. A user can place a call by:

Pressing a Line Key
  • Any keyset can have line keys for one-touch access to specific lines. See Line Keys for more.
Pressing a Loop Key
  • Loop Keys provide a user with one-touch access to the assigned Loop Group. Loop Groups can consist of one or more Line Groups. See Loop Keys for more.
Using Line Dial-Up
  • With Line Dial-Up, a user can select a specific line by pressing INTERCOM and dialing the Line Dial-Up code (#9) followed by the line number (1-64).
Using Direct Line Access
  • Direct Line Access allows a user to access a line by pressing INTERCOM and dialing the line’s extension number (e.g., 101 for line 1, 102 for line 2. etc.). See Direct Line Access for more.
Dialing a Line Group Access Code
  • User’s can also place outside calls by pressing INTERCOM and dialing a Line Group Access Code (90-98). See Line Groups for more.
Line Group Routing
  • If the system has Line Group Routing enabled, user’s get the first available line when they press INTERCOM and dial 9. See Line Group Routing for more.

Dial Buffering

When placing an outside call, extension users can dial an unlimited number of digits. Users are assured that they can use services such as telephone banking without encountering restrictions imposed by the telephone system.

Store and Forward

Store and Forward is an alternate method of placing outside calls in which the system stores (“collects”) the digits a user dials, waits for the user to finish dialing, and then redials the digits on the selected line. Store and forward provides Intercom dial tone to the caller as soon as they dial a line access code or press a loop key, similar to conventional ARS operation. When the user has completed dialing, the system will dial out the call over the connected line after 6 seconds or when the user dials #. Store and Forward can also be an advantage when connected to a T1 service that does not provide line dial tone.

Post dialing for Store and Forward calls is also available. After a user dials using Store and Forward, they can manually dial additional digits. The normal post dialing soft keys (such as AUTO REDIAL [ALND] for Auto Redial) are also enabled.
  • Store and Forward does not apply to line keys, Direct Line Access, or line dial up (i.e., #9 plus the line number).
  • You can use Account Codes with Store and Forward enabled (see Operation below).

Line Appearance Assignment

When a call rings in, or when the user dials using a line group (9 or 90-98), the system assigns a key to the call as follows:
  1. Line Key
    • If there is a line key assigned to the line, the system chooses it first.
  2. Fixed Loop Key
    • If there is no line key, but there is a Fixed Loop key for the line group of which the line is a member, the system chooses the Fixed Loop key. A Fixed Loop key for another group is ignored.
  3. Switched Loop Key
    • If there are no line keys or Fixed Loop keys for the line, the system chooses a Switched Loop key.

Conditions and Defaults


Default Setting

  • Lines 1-12 ring on line keys 1-12 for extensions 300-315. All other extensions are lamp only for lines 1-12. Lines 13-64 do not appear on line keys.
  • All extensions have full access on all lines.
  • Line Group Routing (dial 9) is assigned to Line Group 90 (which contains lines 1-8). Dial 9 works by default. The outgoing line priority for the dial 9 group is as follows:
    • Order 1 = line 8
    • Order 2 = line 7
    • Order 3 = line 6
    • Order 4 = line 5
    • Order 5 = line 4
    • Order 6 = line 3
    • Order 7 = line 2
    • Order 8 = line 1
  • Store and Forward is disabled.
