Handling of the Output Type Of Number
Output Type Of Number is only allowed in a number modification rule together with an ANY
Input Type Of Number. Its meaning is that as a minimum the input Type Of Number needs to be obtained. The following rules apply if optimization is requested in the number modification rule:
The NORMALIZED Output Type Of Number simply returns the fully qualified form of the Number Source.
The FQPN Output Type Of Number requires the Number Source to be modified to a fully qualified private number.
The Extension Output Type Of Number requires the Number Source to be modified to an extension. This is also called a 'forced optimization' and it is subject to the following special rule based on the setting of the RTP variable Srx/Main/UseDisplayExtensionForTonOutExt:
default value 0 (= don't use the display extension for this forced optimization)
value 1 (= use the display extension if available for this forced optimization)
All other Types of Number force an optimization to the requested Type of Number.
Handling of the Optimize Type Of Number
The following rules apply if optimization is requested in the number modification rule:
Optimize Type of Number: None means that to succeed this modification rule requires the type of number of the input number must be the type of number for the output number. Note that this modification rule may still require the optimization logic to be called because at this point in the logic the input number has been converted to a fully qualified number and the input type of number may not have been a fully qualified number. This is put in place to prevent that with this rule a national number from e.g. Germany would be presented to a subscriber in e.g. the USA.
Optimize Type of Number: Extension means that an optimization to extension is requested. Normal logic of getting dialable numbers applies to continue.
For all all other optimization requests: NDAL ensures that the numbering plan identifier of the 'from' Type Of Numbermatches the numbering plan identifier of the optimization request. If they match then the normal logic of getting dialable numbers applies to continue. If the numbering plan identifiers differ then the optimization level for this modification rule (as it is a rule that the administrator usually puts in as the ultimate fallback rule) is reset to None before continuing with the logic of getting dialable numbers.
Handling of Inter-BG Numbers
Number Modification will prevent that private numbers are delivered/known outside of the BG. No Inter-BG number modification request (originating and terminating party are in different BGs) will ever generate a private number.
For inter business group rules (where 2 different business group names are specified), the Output Type Of Number
must be a public Type Of Number: one of ANY
, International, National, Subscriber or Normalized. Inter business group rules with non-public number outputs will be skipped.
The Number Source field in a number modification rule
The Number Source field has the following possible values:
Input Number: this is the number that was obtained by the Lotus Sametime Unified Telephony using the rules described in the Functional Sequence for Number Modification.
Default Home DN: the Default Home DN number provisioned on the specified endpoint is used instead of the Input Number. This rule can only succeed if the dialable number is created of an endpoint that has a Default Home DN number defined.
BG Display Number: the BG Display Number of the business group of the originating party is used instead of the Input Number. This rule can only succeed if the dialable number is created of a subscriber or endpoint whose business group has a BG Display Number defined.
DNM Modifications Prefix Required Rule/ Prefix Required Flag
The Prefix Required flag can be set to indicate that a prefix should be added by the Number Modification library using the entry in the Number Prefixes table that applies to the terminating party.
Presentation Restricted Flag
The Presentation Restricted flag can be set to indicate that the presentation of the number to the terminating party is not allowed.
