Replace Your Unsupported and Outdated Nortel PBX with 3CX Phone System
Switch from your Nortel PBX to a multi-platform, modern phone system. Free for 1 year.

Nortel PBXs are outdated and unsupported. If you’re looking for your next PBX 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 PBX. You can choose your deployment platform; 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. Your phone system. Your way.

It’s free for the first year and includes unlimited extensions, free web conferencing participants and full unified communications features.
