The Destination Codes feature provides destination codes for basic telephone service. The destination code will be used for a call if the dialed or modified (in PAC) digits and the Nature of Address are matching. This field specifies the number configured for this Destination Code. A Destination Code Number is the leftmost digit string pattern identifying a group of Directory Numbers. Destination Codes can be of length 1-15.
Selectable Destination Types for Destination Codes
The destination is a named destination in the E.164 routing data or the BG routing data.
The destination is a feature (also known as service destination).
The first logical step is the definition of the base E.164 numbering ranges used by the system, effectively defining the public number blocks which will be used to reach the subscribers on the system.
Home Location (available only at BG-leve)
When a BG numbering plan is assigned to a location code, other BG numbering plans can route calls to that location code as a destination.
Home Extension (available only at BG-leve)
The next translation step uses the BG Extensions table described
The New Code translation and routing capability allows a Directory Number to be replaced by another DN, and the translation result of the initial DN to be retranslated to the New Code.
The Destination Code/E.164 Code which allows the association with a specified destination has been enhanced to support the New Code functionality. A new Destination Type, New Code and a new field for the New Code string are added. The new Destination Type is implemented for all Numbering Plans.
The following restrictions apply for the New Code Destination Type: If Destination Type is New Code, Nature of Address cannot be Code Index; If Destination Type is New Code, then the TrafficType, Destination Name, and DN Office Code parameters are not applicable.
Example for the use of the New Code Destination Type: The subscriber dials "611" to reach the company´s service bureau. However, the company has several service bureaus in different geographical areas and these are reached via long distance carriers via 800 numbers. Therefore, the 611 must be changed to the appropriate 800 number and then the call needs to be routed to the carrier that "owns" the 800 number.
Valid characters: 0-9, A-E, *, #. Length: 1 - 30.
Code Index Destination
A single Code Index destination can support up to 10K Routing Area/COScombinations.
Time Destination (available only at system-wide leve)
Dependencies of Destination Names from selected Destination Types
Depending on the Destination Type selected, the Destination Name field label will change to a label matching the selected Destination Type as follows:
Table 1. Destination Names depending on the Destination Type selection for Destination Codes
|Destination Type||Destination Name||Comment|
|Home DN||Office Code|
|Invalid Code||Invalid Code Name|
|Home Location||Location Code||only applicable at BG level|
|Home Extension||Home Extension Name||only applicable at BG level|
|New Code||New Code||(Valid characters: 0-9, A-E, *, #. Length: 1 - 30)|
|Code Processing||Code Index Name|
|Time Destination||Time Destination||only applicable at system wide level|
|Calling Location||Calling Location|
Available Services for Destination Codes (selected Destination Type: Service)
Table 2. Definition and Description of Services listed in Service List dialog for Destination Codes:
|Abbreviated (Displayed) Destination Name ||Full Destination Name||Service Type ||Destination Definition|
|Remote CF||Remote Call Forwarding||Dest. Code||The Remote Call Forwarding (RCF) feature allows calls incoming to Remote Call Forwarding subscriber DNs to be forwarded to the remote forwarding address, unless the maximum simultaneous calls allowed for forwarding is reached.|
|RFA||Remote Feature Access||Dest. Code||Remote Access is a common function that is used by any feature/service that wants to allow it. The PIN and RFA need only be assigned once and then can be shared by all services allowing Remote Access.|
|RACF||Remote Activation of Call Forwarding||Dest. Code||The Remote Activation Call Forwarding (RACF) feature allows a subscriber who has any of the call forwarding feature variants to activate/deactivate and change the redirect number (for CFV) from another line. The RACF subscribers access their call forwarding feature by dialing the RACF DN, as provided by the operating company. The subscriber receives an announcement requesting them to enter their home DN, followed by an announcement requesting their Personal Identification Number (PIN). Upon verification of the home DN and PIN, an announcement is played requesting the Service Access Code for the type of call forwarding procedure to be attempted.|
|MLHG||Multiline Hunt Group||Dest. Code||"Multiline Hunt Group (MLHG) features permit calls to be routed to an idle line within a group of specified lines (i.e., a multiline hunt group). Each individual line must have its own private Directory Number (DN). A call is placed to a MLHG by dialing the Pilot DN. When a call is placed to a MLHG, the attempt to terminate the call begins with the line (member) designated by the Pilot DN, based on the hunt groups hunt method (sequential or circular). When all lines are busy, overflow treatment is provided to an intercept treatment of Busy Tone. A media server is required for audible treatment. The lines in a single MLHG cannot be a mixture of different business groups nor can they be a mixture of business groups and non-business groups.The Lotus Sametime Unified Telephony supports groups of stations that can be accessed through a pilot station number (pilot hunt group) or through a call number of a controlling station (master hunt group). With a pilot hunt group, dialing the pilot number (station) for a group provides access to the pilot group. Calls are not distributed to the pilot station; this number is used only as an access number to the hunt group. With a master hunt group, dialing the master number (station) for a group provides access to the master hunt group. Calls are distributed to the master station; the master station also has access to certain features that control the hunt group, such as call forwarding.|
|Emergency Callback||Callback Number for Emergency Calling||Dest. Code||The Destination Code Service value EnhEmncyCBSvc is used to define a Callback Number for Emergency Calling Subnets. The Service can only be assigned to a Vacant DN or en-bloc to leading digits of Vacant DNs. In case an Emergency Caller has to be called back from the E911 station, such a DN then can be used for the callback, if so entered into the caller's Emergency Calling Subnet."|
|Call Pickup Dest||Call Pickup B side||Dest. Code||Group Call Pickup B side service is invoked for every call to a member of a call pickup group, even if there is no user intending to pick up the call via the group call pickup feature.|
The Call Pickup B service requires computation time to process the called party subscriber information and requires memory to store the call information in a shared memory location for the Call Pickup A service to access it. This shared memory update can impact the basic call because of shared memory synchronization.
|BG MainNumber ||Business Group Main Number||Dest. Code||The Business Group Main Number is the published number for a Business Group (BG).|
|BG Hot Desking||BG Hot Desking Service ||Dest. Code||The BG Hot Desking (HD) service specifies either the Home DN or Remote DN of a Business Group Line (BGL) whose members/subscribers will be able to activate HD through an access code.|
Range of Destination Codes
Destination codes can be provisioned with a range of codes when creating destination codes via the Add Range
If this option is chosen, the user is promoted to specify the 'begin code' and 'end code' (the 'end code' can have same value as the 'begin code').
This operation results in creating a number of destination codes starting from 'begin code' to 'end code'.
For Example: If the values of 'begin code' is 1 and the value of 'end code' is 9, then 9 destination codes will be provisioned in the system.
