## Use case

10
Most modern (business) voice phones have the capability to do comfortable LDAP directory look-up like:
11
12
  - Directory search by alphabet letters
13 25 Jörg Ebeling
  - Reverse lookup for in- or out-bound calls
14 1 Jörg Ebeling
  - Reverse lookup by entering parts or the phone number

16 15 Jörg Ebeling
Unfortunately, most of the 'smaller' companies (i guess companies beyond 100 employee) don't have an 'enterprise' LDAP directory, much less than private persons.  
17 25 Jörg Ebeling
Most of such companies do have something like a cloud address-book, often based on WebDAV / CardDAV (i.e. Nextcloud, Ownlcoud, Baïkal, Daylite, ...).  
18
This is, where this gateway might make your live easier.

If this program get started on some kind of hardware (Linux, Windows, MacOS, Raspberry Pi, ...), it will do the following:

21 31 Jörg Ebeling
1.  Synchronize your CardDAV Server to a small local database cache
22 24 Jörg Ebeling
2.  Answer on LDAP requests from your voice phone(s)
23
3.  Ask your local database cache for the LDAP requested phone-book entry
24 1 Jörg Ebeling
4.  Response with the matching CardDAV contacts, as LDAP results to your phone.

## Features
27
28
  - Query your CardDAV address book(s) by entering the alphabetic letters (or parts of the telephone number) in your (LDAP capable) phone (and dial one of the matching numbers).
29 30 Jörg Ebeling
  - Reverse lookup of inbound calls and display matching contact information on the phone.
30 31 Jörg Ebeling
  - Work with local formatted (non- E.164) CardDAV entered phone numbers like: '040-123456' or '001 807 1234567' as well as '+49 (0)40 1234567-8' = no need to format the phone numbers of your CardDAV contacts in a special notation.
31 1 Jörg Ebeling
  - Supports internal (extension) phone numbers.
32 25 Jörg Ebeling
  - Support dial prefix for external line.
