Suggestions for Hosting a PBX System at Home

VoIP

Hello everyone,

I hope you’re all doing well!

I’m looking for suggestions on hosting my own PBX system at home on my Proxmox server. My primary goal is to learn more about PBX systems and VoIP phones. For now, I’m using VoIP.ms just to purchase a phone number.

My main question is about 3CX. I really like the UI and apps that 3CX offers. Is it realistically possible to host 3CX at home if I have a dynamic public IP? Has anyone found a way to run it successfully without opening any ports at all? I know that accessing the 3CX web UI via a Cloudflare Tunnel works without exposing ports, but I’m curious if anyone has managed to get the other required services working this way too.

That said, I’m not tied to 3CX. I’m open to any PBX solution that I can self-host at home to gain experience. I run a small MSP and I’m trying to expand my knowledge so I can eventually offer VoIP services to my clients.

Thanks in advance for your insights!

I can’t specifically comment on 3CX, but I do this with FreePBX and it works without any issue on a dynamic WAN address. There isn’t a way to avoid forwarding ports, however. At least you need to forward a high range of UDP ports to your PBX for RTP. I also accept sip traffic specifically from my voip provider’s IPs.
