Who’s calling you?


We recently installed a phone system that required in excess of 5000 centrally held address book entries with regular management in terms of addition, deletion and edit to be available on every handset.

The address book required to make outgoing calls and, more importantly, to match an incoming call to an entry in the address book to display the caller’s name on the handset.
This is exactly the way a mobile phone works, the client required the same features on their office system.
The challenge was the 5000 entries in the address book, and the answer was an LDAP. 

(LDAP is an acronym for Lightweight Directory Access Protocol, which is a convoluted way of saying it’s an electronic card index. You can read more about LDAP here).

The Grandstream range of PBXs include an LDAP server as standard, that is capable of storing multiple LDAP address books, each capable of an almost unlimited number of entries.  This allows separate address books based on, for example, department as well as a central address book for the company as a whole.

Every Grandstream handset is an LDAP client, even the softphone app available for android and iPhone.

The address book is maintained centrally and changes are immediately available because there is are no uploads, downloads or synchronisations required.

The downside, if the original address book is held somewhere else, like Exchange365, then you have to maintain both after an initial export/import.

If you think an LDAP address book might be useful to your company then please contact us.
