To support creating Modifications table rules where a default Home DN of an endpoint is chosen over the input number to be presented to an endpoint, the endpoints table needs to allow provisioning a default Home DN.
The Default Home DN is used in 2 ways:
First to be able to provide a public number to a gateway when either no public number can be created (subscriber only has a private number) or the public number that would be presented is not in the range of DNs that the public operator expects to receive.Parent topic: Display Number Modification
Second to be able to provide a correct definition when creating a calling party number to be sent to a public gateway. By using the Default Home DN's Definitions table entry instead of the translated number's Definitions table entry (which may and should not even exist as it is NOT a number known to Lotus Sametime Unified Telephony), the Display Number Modification library can optimize the calling party number correctly based on the Definitions table entry matching the default Home DN.
Example: if a subscriber makes an international call via a local gateway, then the calling party number to be provided to the gateway should still be in local or national number format.
