Key Mode

Each phone is configured with 2 Intercom buttons which cannot be changed. It is also configured with line appearance buttons for specific lines using the Number of Lines settings and individual button programming.

•Internal calls are made by selecting one of the two Intercom buttons provided on each phone and then dialing the number of another extension or of the system feature required.

•External calls are made by selecting one of the line appearance buttons programmed on the phone and then dialing the external number required.

•If the user dials without first selecting an Intercom or Line button, the user's automatic line selection setting is used to determine which button, if available, gets used.

•If an external number is added to contacts, when dialing, it rings on the first available line from the ALS. If there is no line added to the ALS, the call is not made. If it is an internal number it dials on the intercom.

 

PBX Mode

Each phone is configured with 3 call appearance buttons (2 only on ETR phones). These can be used to make both internal and external calls. The dialing of an external call can be indicated by the dialing starting with a specific prefix (9 or 0) if required, otherwise any number not matching an internal extension or function is assumed to be external.

The line used for an outgoing external call is determined by configuration settings. ARS Selectors are created which can be groups of lines or specific functions using any available ISDN lines. Different external number prefixes are then mapped to those ARS Selectors. When a user dials an external number, it is matched to a selector and uses the function and one of the lines specified by that selector. For SIP trunks set to call by call mode, each call by call entry also has an ARS selector settings which allows it to also be used for outgoing calls.

Line appearances can still be used to make and answer calls on a particular line but are not added by default.

All calls go through intercom. This is true for internal and external calls (ARS). If you enable a prefix for external numbers, then you must be manually modify the number stored in contacts. If the number was not added before the prefix option in the Manager was selected, you have to add the number with the selected prefix.

 

Dialing Restrictions

In both modes, the system uses a number of methods to control the external numbers which users are allowed to call.

•Allowed Number Lists / Disallowed Number Lists
These lists are used in define numbers that can or cannot be dialed. Users are then associated with the different lists.

Allowed Numbers

Each allowed list contains external telephone numbers that members of the list are allowed to dial regardless of any other call barring. The users allowed lists override any disallowed lists of which they are also member and the user's Outgoing Call Bar and Outgoing Call Restrictions settings.

There are eight lists, each containing up to 10 numbers. Each number can use the telephone dialing digits 0 to 9, *, # and can be up to 28 digits long. You can also use the ? character as a single digit wildcard.

Disallowed Numbers

Each disallowed list contains external telephone numbers that users who are members of the list are not allowed to dial.

Numbers in the disallowed lists of which a user is a member are overridden if they also appear in the allowed numbers lists, emergency number list of which the user is a member and also by marked system speed dials.

There are eight lists, each containing up to 10 numbers. Each number can use the telephone dialing digits 0 to 9, *, # and can be up to 28 digits long. You can also use the ? character as a single digit wildcard.

Emergency Numbers

You can enter 10 emergency phone numbers into this list. This list is applied to all users and overrides any dialing restrictions that may also be applied to the users. Use of numbers in the list can be viewed using a 911-View/E-View button.

•Account Codes
Each user can be configured to need to enter a valid account code whenever they make an external call.

•Outgoing Call Restrictions
For each user, the type of external calls that the user is able to make can be configured.

•Marked Speed Dials
When a user uses a stored system speed dial number, the actual number dialed is subject to all the call barring methods as if the user had dialed the number directly. However system speed dials set as 'marked speed dials' override any call restrictions.  

•Night Service
When the system is set to night service, any users in the Night Service Group need to enter the system password when making an external call.
