Nortel PBXs are outdated and unsupported.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.
Run on-premise: Windows or Linux
Self host with YOUR cloud account
Clients for Windows, Mac, iOS and Android
No vendor lock-in
