Replace Your Unsupported, Outdated Nortel PBX with 3CX

Switch from your Nortel PBX to a multi-platform phone system.

Nortel PBXs are outdated and unsupported. If you’re looking for your next business phone system then look no further. 3CX is a software-based, open-standard phone system which offers complete UC features out of the box.

Proprietary PBXs, such as Nortel, are very limiting when it comes to deployment platform, IP Phones, Gateways and SIP Trunks. Not so with 3CX’s VoIP PBX. You choose where to deploy; whether on-premise on Windows or Linux or in the cloud. The choice of IP Phones, SIP Trunks and Gateways is also entirely up to you. Replace your Nortel Norstar or Nortel Meridian system with a modern, feature-rich IP PBX. Your phone system. Your way.

Includes unlimited extensions, free web conferencing participants and full unified communications features – no add-ons or expansion modules.
