When an employee is removed from AD, their 3CX access can be removed right away—no waiting for a manual cleanup.
No more repetitive extension maintenance. Fewer human errors. Less firefighting.
Archive voicemails and recordings before deactivation so you don’t lose critical communications.
Works whether you have 10 users or 10,000—your process stays the same, just automated.
Every org says they’ll “update the phone system later.” Then someone leaves, their extension still works, voicemails get lost, and IT burns time chasing small changes that never end.
3CX Active Directory Sync eliminates the busywork and the risk by keeping 3CX aligned with AD—continuously, on a schedule you control. It securely connects to your domain via LDAP, compares AD users/extensions against 3CX, and automatically handles mismatches so your phone system reflects reality without manual cleanup.
Add new hires faster. Remove ex-employees immediately. Keep names, emails, and extension-related details consistent. And when you deactivate an extension, you can archive critical voicemails and recordings first so you stay compliant and don’t lose evidence, history, or customer context.
Set it once. Trust it every day.
