Link a number to a contact whatever it includes international code in it or not

Closing this task in a global Jira cleanup process

Aspects to consider about this problem:

• Calls are

  • incoming with a callerid that is supposed to be normalized by the SBC, potentially with a reverse lookup to know the callerid name

  • outgoing with a callerid set in the user

• Phone number can be found in

  • the call logs

  • the DID form

  • the CallerID set in user/outgoing calls/trunks forms

• Directories are:

  • the personal directory

  • the third-party directories (google, office365…)

    • Lookup strategy 1: make two lookups, one with the number verbatim, another with the number normalized

    • Lookup strategy 2: search for the last digits (how many?) and find numbers matching the location of the user from the results

  • tenant directories (LDAP, internal phonebook…)

  • call forwards

• Numbers that are already stored in the engine from previous versions will need to be converted to a normalized format

• Numbers should be displayed in the form best understandable by the user (australian user = display australian number as local number vs. peruvian user = display australian number as international number)

• SBC normalization may need information about callerid format used by each provider
