Parameter

Description
PBX calling number screening This field only applies to PBXs with a Call Agent signaling type set to ISDN PRI or SIP. Specifies whether the calling number provided by the PBX on outgoing calls is used as the calling party number and/or charge number. This field does not apply if both the Calling party number and Charge number fields are specified; the configured numbers always take precedence. Choose Use default or specify a value:
  • No screening
    Use the number supplied by the PBX, whatever the number is.
  • Valid format (North America only)
    Use the number provided by the PBX if it meets the standard North American 10 digit format.
  • Owned DN
    Use the number provided by the PBX if it matches the PBX's Directory number, a number in one of the PBX's DID Range objects, or one of the PBX's DISA Number objects.
  • Ignore provided number
    Never use the number provided by the PBX.
MADN call limit algorithm This field applies only for a MADN. Specifies how the NE should limit the total number of concurrent incoming calls to the MADN. When this limit is reached, any further incoming call attempts will receive a busy indication. Note that an incoming call to the MADN counts against this limit only if it is connected to a Business Group Line that is a direct child object of the MADN; calls connected to another MADN or MLHG that is a child of the called MADN are not counted. Choose Use default or specify a value:
  • Total calls cannot exceed number of members
    The total number of concurrent incoming calls to the MADN, including both calls connected to Business Group Line MADN members and queued calls, cannot exceed the number of lines configured as MADN Members. Note that some calls may be queued if one or more lines are busy with outgoing calls or direct-dialed incoming calls to a MADN Member.
  • Total calls cannot exceed specified value
    The total number of concurrent incoming calls to the MADN, including both calls connected to Business Group Line MADN members and queued calls, cannot exceed the number specified in the Call limit value field.
  • Queued calls cannot exceed specified value
    The total number of queued incoming calls to the MADN cannot exceed the number specified in the Call limit value field.
MADN call limit value This field applies only for a MADN. This field appears only if Call limit algorithm is set to Total calls cannot exceed specified value or Queued calls cannot exceed specified value. Choose Use default or specify the maximum total number of incoming calls (minimum 1) or the maximum number of queued calls (zero indicates that calls will never be queued).
Number Validation and routing attributes This field applies for an Individual Line, PBX or Business Group. You can override it for a Business Group Line within the group using the following field. Attributes used to determine how a call made by the subscriber is routed to the network. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or, if required, select one or more of the following values:
  • Pre-paid / off-switch calling card subscriber
    The subscriber uses a pre-paid or off-switch calling card service. The NE must check with an external pre-paid billing platform before routing the call, to ensure that the subscriber is permitted to make this type of call (local, long-distance, international etc.)
  • Fax / modem subscriber
    The subscriber can make fax or modem calls (for which compression should not be used) in addition to standard voice calls. This attribute is typically used to route calls for this subscriber over TDM trunks (such as ISUP) in preference to SIP trunks.
  • Nomadic subscriber
    The subscriber uses VoIP service and may do so from multiple locations. This attribute is typically used to route emergency (911) calls from this subscriber to a VoIP Emergency Call Services system that can provide details of the subscriber's current location.
Business Group Line Number Validation and routing attributes Attributes used to determine how a call made by the subscriber is routed to the network. Choose Use default or, if required, select one or more of the following values:
  • Pre-paid / off-switch calling card subscriber
    The subscriber uses a pre-paid or off-switch calling card service. The NE must check with an external pre-paid billing platform before routing the call, to ensure that the subscriber is permitted to make this type of call (local, long-distance, international etc.)
  • Fax / modem subscriber
    The subscriber can make fax or modem calls (for which compression should not be used) in addition to standard voice calls. This attribute is typically used to route calls for this subscriber over TDM trunks (such as ISUP) in preference to SIP trunks.
  • Nomadic subscriber
    The subscriber uses VoIP service and may do so from multiple locations. This attribute is typically used to route emergency (911) calls from this subscriber to a VoIP Emergency Call Services system that can provide details of the subscriber's current location.
Distinctive alerting This field applies only when the template is being used to configure a Business Group. Specifies whether a distinctive ring tone is used for incoming calls to lines in this Business Group, to identify either internal calls (from within the Business Group) or external calls. Distinctive alerting applies both to ring tones when the called number is not busy and to Call Waiting tones when the called number is busy. For SIP subscribers, use of distinctive ring tones depends on the support provided by the SIP device. The distinctive ring tone used is different from that used for the Priority Call service. If both services are in use and an incoming call is from a number in the subscriber's own Priority Call list, the Priority Call ring tone is used in preference to the business group's distinctive alerting ring tone. Values:
  • None
    Distinctive alerting is not used.
  • External
    A distinctive ring tone is used for incoming calls from external numbers.
  • Internal
    A distinctive ring tone is used for incoming calls from internal numbers.
Service suspended This field applies for an Individual Line, PBX or Business Group. You can override it for a Business Group Line within the group using the following field. Specifies whether service for this subscriber is currently suspended (the subscriber is prevented from making or receiving calls). This field appears only if Number status is set to Normal, Ported to, or Non-geographic. For an Individual Line with Teen Service enabled, this field controls service on all of the Teen Service lines as well as the primary line. It is not possible to suspend service on a Teen Service line separately from the primary line. Values:
  • None
    Service is not suspended: the customer can make and receive calls as normal.
  • Incoming calls
    The subscriber is prevented from receiving incoming calls, except that he or she can still receive calls from the operator.
  • Outgoing calls
    The subscriber is prevented from making calls, except that he or she can still make calls to emergency services or to the designated suspended service access number.
  • Incoming and outgoing calls
    The subscriber is prevented from making or receiving any calls, except for calls to emergency services or to the designated suspended service access number.
Business Group Line service suspended Specifies whether service for this subscriber is currently suspended (the subscriber is prevented from making or receiving calls). This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default to use the setting from the parent Business Group, or specify a value:
  • None
    Service is not suspended: the customer can make and receive calls as normal.
  • Incoming calls
    The subscriber is prevented from receiving incoming calls, except that he or she can still receive calls from the operator.
  • Outgoing calls
    The subscriber is prevented from making calls, except that he or she can still make calls to emergency services or to the designated suspended service access number.
  • Incoming and outgoing calls
    The subscriber is prevented from making or receiving any calls, except for calls to emergency services or to the designated suspended service access number.
Local CNAM name This field applies only when the template is being used to configure a Business Group. A name used to identify this Business Group when providing Calling Name Delivery information on a call from this Business Group to another subscriber on the switch. You can override this setting in the Caller ID Services object for each Business Group Line in the group if necessary. Specify a name of 1 - 15 characters, or leave the field blank if you do not want to specify a calling name.
Force LNP lookup This field is used to force an LNP lookup for a particular subscriber. This is typically only used when a ported subscriber is moving. During the period where the subscriber number is configured as active on two switches, the number portability database is the definitive reference for which number is active. If this field is set to True, LNP information for this subscriber will never be cached, so a lookup is required every time a call arrives for the subscriber. The typical sequence used for porting a subscriber is as follows.
  • Set force LNP lookup flag on original subscriber record
  • Create new subscriber record on recipient switch, also setting force LNP lookup flag
  • Update LNP database at time when line is to be moved.
  • Clear force LNP lookup flag on new subscriber record.
  • Delete old subscriber record or mark it as "Reserved, ported out" as required.
This field is valid only when Number Status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify a value:
  • True
  • False
Timezone Specifies the timezone for this subscriber. Choose Use default or specify a value:
  • Unknown
  • EEST (+2)
  • CET (+1)
  • GMT (+0)
  • WET (-1)
  • GMT-2 (-2)
  • GMT-3 (-3)
  • AST (-4)
  • EST (-5)
  • CST (-6)
  • MST (-7)
  • PST (-8)
  • ALST (-9)
  • HST (-10)
  • SST (-11)
Adjust for Daylight Savings This specifies whether the time for this line should be automatically adjusted for daylight savings time. This moves the subscriber's time forward one hour at 2am (local time) on the second Sunday in March, and back one hour at 2am (local time) on the first Sunday in November. Choose Use default or specify a value:
  • True
  • False
Locale The language variant used for voice announcements played to this subscriber. Values:
  • English (US)
  • English (UK)
  • English (Canadian)
  • French (Canadian)
  • Spanish (Latin America)
  • User Defined 1
  • User Defined 2
Line Class Code 1 - 20 This field does not apply when the template is being used to configure a Business Group Line. The field name for each Line Class Code appears as LCC n - description (showing the index value in the range 1-20 and the configured description, if any). A Line Class Code is used as a match attribute in number validation and/or routing to provide additional options for routing calls originating from this subscriber. If you need to perform specific routing for this subscriber's calls, set this field to a value used as a match value for the Line Class Code in the appropriate Number Validation Entry or Routing Action. Select Use default, or specify the Line Class Code as an integer value in the range 0 - 2147483646. You cannot select Use default if the corresponding Line Class Code object has Allow inheritance set to False; you will have to specify a value. Alternatively, if one or more valid values have been configured in the Line Class Code object, you can select a specific value from the list of valid values by clicking on the ellipsis symbol at the end of the field. Either scroll down the alphabetic list of code value descriptions to select the value you want, or type the first few letters of the code's description so that the alphabetic list scrolls to select the entry you want..
Long distance carrier This field does not apply when the template is being used to configure a Business Group Line. The long distance carrier ID (PIC1) used by default for this subscriber. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number.
IntraLATA carrier This field does not apply when the template is being used to configure a Business Group Line. The intraLATA carrier ID (PIC2) used by default for this subscriber. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number.
International carrier This field does not apply when the template is being used to configure a Business Group Line. The international carrier ID (PIC3) used by default for this subscriber. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number.
Calling party number The 10-digit number, if any, to be sent in signaling messages for this subscriber in place of the subscriber's directory number (for example, if the directory number corresponds to an outgoing-only line and should be replaced by the number of another line that accepts incoming calls).
Business Group Line long distance carrier This field applies only when the template is being used to configure a Business Group Line. The long distance carrier ID (PIC1) used on this Business Group Line. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number. If the Business Group includes lines from two or more Rate Centers, you should use the Business Group default setting, which identifies your own long-distance carrier ID. Some services specific to Business Groups (such as internal Caller ID, distinctive alerting, or flat rate billing for intercom calls) may not work correctly if calls within the Business Group are routed over other carriers.
Business Group Line intraLATA carrier This field applies only when the template is being used to configure a Business Group Line. The intraLATA carrier ID (PIC2) used on this Business Group Line. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number. If the Business Group includes lines from two or more Rate Centers, you should use the Business Group default setting, which identifies your own intraLATA carrier ID. Some services specific to Business Groups (such as internal Caller ID, distinctive alerting, or flat rate billing for intercom calls) may not work correctly if calls within the Business Group are routed over other carriers.
Business Group Line international carrier This field applies only when the template is being used to configure a Business Group Line. The international carrier ID (PIC3) used on this Business Group Line. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or specify the carrier ID as a 4-digit number.
Line selection method This field applies only when the template is being used to configure a PBX. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Specifies the order in which the NE allocates lines for incoming calls to the PBX. This should be different from the order used by the PBX itself to allocate lines for outgoing calls, to minimize glare. Values:
  • Lowest available
    Use the lowest-numbered line that is free.
  • Highest available
    Use the highest-numbered line that is free.
  • Least recently used
    Use the line that has been free for the longest period of time.
Dialtone supported (pre-R4.0) This field has no effect when used on an NE which is running V4.0 or later. This field applies only when the template is being used to configure a PBX. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Specifies the types of line for which the PBX provides dialtone to the caller. If this option is not selected, the MetaSwitch NE provides dialtone on lines of that type. If required, select the following value:
  • E & M wink start
Ringback supported (pre-R4.0) This field has no effect when used on an NE which is running V4.0 or later. This field applies only when the template is being used to configure a PBX. Specifies whether the PBX provides audible ringing tone to the caller. Values:
  • True
    The PBX provides ringback.
  • False
    The switch must provide the audible ringing tone, and the call is not cut through to the PBX until it is answered.
This parameter is ignored if the PBX Lines use ISDN signaling over an ISDN Primary Rate Interface that is configured to support ringback. The switch provides ringback only if neither the PBX nor the ISDN PRI supports it.
Fix bits This field applies only when the template is being used to configure a PBX. A series of options that control the details of how the MetaSwitch NE interoperates with the PBX. If required, select one or more of the following values:
  • 10 digit max ANI
    The PBX supports a maximum ANI length of 10 digits. If this fix bit is set and a calling number is longer than 10 digits, no ANI parameter is sent to the PBX. If the fix bit is not set, the ANI parameter is sent regardless of its length.
  • Always 10 digit ANI
    The ANI sent to the PBX must be 10 digits. If this fix bit is set and a calling number is shorter than 10 digits, the NE pads it with zeros. If the fix bit is not set, the ANI parameter is sent unchanged regardless of its length.
ANI / DNIS format This field applies only when the template is being used to configure a PBX. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. The format of ANI and DNIS digits outpulsed to the PBX, identifying the calling number and/or the PBX Line for which the call is intended. This is a string of the format prefixDNISseparatorANIsuffix or prefixANIseparatorDNISsuffix. The default is *ANI*DNIS*.
  • Each of prefix, separator and suffix is a string of 1 - 5 digits, or may be omitted. The valid digits are 0 - 9, * and #.
  • At least one of ANI and DNIS must be included.
  • No other characters (for example spaces used as separators) are valid.
Deliver ISDN User Provided Number on emergency call This field does not apply when the template is being used to configure a Business Group. Specifies whether to use an ISDN User Provided Number or the subscriber's directory number when connecting an emergency call. This field appears only if the Call Agent signaling type field is set to ISDN PRI. Values:
  • True
    If an ISDN User Provided Number is available, send this as the calling number when connecting the call.
  • False
    Remove the ISDN User Provided Number and send the subscriber's directory number instead.
Use static NAT mapping This field does not apply when the template is being used to configure a PBX. Specifies whether the NE should perform Network Address Translation on the contents of messages sent to this subscriber. This field appears only if Call Agent signaling type is set to SIP. Values:
  • True
    Select this value if the subscriber is on a separate IP network from the NE and there is no Session Border Controller to provide the translation.
  • False
    Select this value if the subscriber is on the same IP network as the NE, or if they are on separate networks and there is a Session Border Controller associated with the firewall between the networks.
Maximum call appearances The maximum number of simultaneous call branches in which the subscriber can participate. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP. Choose Use default or specify a value. When the subscriber's SIP phone registers with the NE, creating a Registered SIP Binding object, this value determines the number of SIP Call Appearance child objects of the Registered SIP Binding. When the template is being used to configure a PBX, this field determines the PBX's Default maximum call appearances for PBX lines; you can override this for a specific PBX line if required.
Maximum permitted contact refresh interval This field does not apply when the template is being used to configure a PBX. The maximum time for which a SIP registration from this subscriber remains valid. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP. Choose Use default or specify a value. This time corresponds to the Expires header on the SIP request; the SIP phone will be disconnected if the user does not re-register within this time. The SIP phone may specify a shorter interval when registering, but if it specifies a longer interval or does not specify one, the value in this field is used in the SIP response. If the SIP phone specifies an interval lower than 3600 seconds (1 hour), this field must be set to the exact value specified by the SIP phone; otherwise the registration attempt is rejected and the SIP phone is disconnected.
VQM call logging This field appears only if VQM call logging is enabled on the Call Agent (in the Call Logging object). Specifies whether Voice Quality Management (VQM) data, if available, should be recorded for calls to or from this subscriber. You can view this data using the Call Logs function in the NE craft interface, as described in the IS, CA and MG Craft Interface Guide. Choose Use default or specify a value:
  • True
  • False
If you use this template to configure a Business Group, you can override this value for one or more Business Group Lines in the group if required.
