The available numbers (from which new telephone numbers are assigned)
are stored in the database. The range of available numbers can be
initialized or updated using the create_numbers.py tool:
sudo env/bin/python src/metaswitch/ellis/tools/create_numbers.py <options>
where the options are:
--start <nnn>to specify the initial directory number, e.g., 6505550000.--count <nnn>to specify how many numbers should be made available, e.g., 1000.--pstn(optional): if present, the command affects available PSTN numbers; if absent, it affects available internal numbers.--realm <name>(optional): the realm in which the directory number resides; if absent, it defaults to the home domain.
