In most offices, the extension list is a printout stuck to the wall that went out of date the week after it was made. An IP phone directory fixes that. Staff look up colleagues, suppliers and key customers on the phone itself or the PBX, and dial with one press. This guide explains the common ways to build a company phonebook for IP phones, which one suits which office, and the directory tools in Voxdial IP PBX.
What an IP phone directory is
An IP phone directory is a list of names and numbers that staff can search and dial without typing the full number. It usually covers:
- Internal extensions: every colleague by name and department.
- Frequent external numbers: suppliers, banks, transport, branch offices.
- Important customers or partners: numbers people call often.
The aim is simple: fewer wrong numbers, faster calls and one list that everyone shares.
Four ways to build a company phonebook
| Method | How it works | Best for | Watch out for |
|---|---|---|---|
| Local contacts on each phone | Contacts saved on the handset itself | Very small offices | Every phone has a different list; changes must be made phone by phone |
| Remote phonebook (XML) | The phone downloads a phonebook file from a web address | Offices of any size with a central list | The phone model must support it, and the file must be kept up to date |
| LDAP directory | The phone searches a company directory server | Companies that already run a directory such as Active Directory | Needs a directory server and phone support |
| PBX directories and speed dials | Lists kept on the PBX, used through codes or consoles | Shared numbers, reception and call centres | Not every list appears as a searchable menu on the phone |
Most offices use a mix: names on the phone for internal colleagues, and shared lists on the PBX for external numbers.
Directory tools in Voxdial IP PBX
Voxdial IP PBX keeps several shared lists that act as the company’s phonebook.
Extension display names
Every extension has a display name, the caller name shown for that extension. When a colleague calls, the phone shows “Accounts – Priya” rather than just “214”. Keep display names consistent, for example department then name, so they make sense on every screen.
Speed dial
Speed dial lets you set short codes for full phone numbers, so staff reach frequently called numbers with a brief code instead of the whole number. Each entry has a code, an optional name and the phone number. Choose codes that do not clash with extensions or feature codes; the dial plan guide shows how to keep number ranges apart.
Address book
The address book is a shared list of named contacts and numbers. Each contact can carry a VIP level from 1 to 9, which gives known important callers priority when they reach a call queue. You can search it, add contacts one by one, and import or export the whole list as a CSV file. The number of contacts is limited by your account.
Quick contacts for agents
In Voxdial Contact Center, quick contacts are a shared directory that agents dial with one click. Each entry has a name, a number and an optional category such as “Branches” or “Escalation”, and the list can be imported from CSV.
Directory settings on the phones
Phone-side directory features, such as a remote phonebook web address or an LDAP server, are settings on the phone. Setting them by hand on every handset is slow and easy to get wrong.
With IP phone auto provisioning, each phone is registered by its MAC address and gets its settings from the configuration template for its model. That means any phone setting you standardise is set once in the template rather than on each desk. Ask BitVoice which directory options your phone models support before you decide on a method. How to choose an IP phone lists the features worth checking when you buy phones, including a clear screen for directory search.
How to set up a company phonebook
- Clean the data first. Export what you have into one spreadsheet. Remove duplicates, old staff and wrong numbers.
- Agree a naming format. For example “Department – First name Last name”. Use the same format for extension display names.
- Split internal and external. Internal colleagues come from extension display names; external numbers go into the address book, speed dials or quick contacts.
- Load shared lists by CSV. The address book and quick contacts both take CSV imports, so a clean spreadsheet loads in one step.
- Give one person ownership. Someone in admin or IT updates the list when staff join or leave, and exports a CSV backup each month.
- Add BLF keys for reception. A directory tells reception who to call; busy lamp field keys tell them whether that person is already on a call.
Keep the directory safe
A company phonebook is personal data. Customer and staff numbers should only be visible to people who need them, and the list should be kept current so old entries are removed. Use account permissions on the PBX so only administrators can edit or export the lists.

FAQs
What is an IP phone directory?
It is a searchable list of names and numbers that staff use to find and dial colleagues and contacts without typing full numbers.
Can I import my existing contact list?
Yes. In Voxdial the address book and quick contacts both import CSV files, so you can load a cleaned spreadsheet in one step.
What is the difference between speed dial and the address book?
Speed dial gives a short code to a full number so it can be dialled quickly. The address book is a searchable shared contact list where contacts can also carry a VIP level for queue priority.
Do I need LDAP for a company phonebook?
No. LDAP suits companies that already run a directory server. Smaller offices often manage well with extension display names, speed dials and shared PBX lists.
