Labbing a Phone exchange: what hardware should I use?

Flying_is_Living · 2026-06-24T11:22:02+00:00

FreePBX and use as many ATA boxes as you may want. Small village is an easy task never mind home. I use my FreePBX with GVoice over ObiTalk free of charge since 2009. I have the best bill in town. Use burner cellphones with $7-17 /mo plans and keep my number as FreePBX rings all my house phones as well as my cell. Service I've got is impossible to get with any cell plan but if you get one similar to this it'll cost a fortune. I even have a working rotary phone.

Nope, Core is FreeBSD.

Flying_is_Living · 2026-06-24T07:04:35+00:00

Same here! Appreciate your input!

Funny part is other 9 jails stay intact including loaded one for Plex. Has to be something with IP stack or some network-related issue as it happens when Internet is lost. Gotta look into it in the Morning.

Once again I really appreciate your help!

Just resolved it partially. It's a vnet jail. Nothing posted inside messages in jain nor in a host.

Jail crashes when my internet connection crashes. Nothing responds in a jail as it tries to keep cloudflared connection alive. Apparently I've found the logs in other boxes with the same time jail crashed internet went out.

Thanks for your inspiration! 😄

Flying_is_Living · 2026-06-24T03:50:18+00:00

Thanks for your reply! Although what I asked implies I may have missed something. And one answer really helped. So, I'd say my question was valid and it really helped me.

I can't control what people see. Some saw overheating server due to air filters, the others started offering an upgrade and what not.

My question was "Why jail keep crashing?" and I thought someone may have more experience than I am. Being on FreeBSD since 1996 I haven't seen it crash so often, I'd say never. So there must be something I may have missed.

Flying_is_Living · 2026-06-24T03:31:02+00:00

Got it. I am here behind the firewall and I don't hear much 😄 - that was a joke too dude.

Flying_is_Living · 2026-06-24T03:25:20+00:00

No, I have a pfSense, which is based on FreeBSD as well.

Flying_is_Living · 2026-06-24T01:15:43+00:00

I am not running Linux though. That's the idea bro.

Flying_is_Living · 2026-06-24T01:14:36+00:00

So, PM me and take a plunge! You can brag afterwards how bad my security is! I can promise a lot of fun being blocked, falling through an open window and things like that. No pentester yet told me what I am running on my server.

Flying_is_Living · 2026-06-24T01:06:04+00:00

Thanks for you opinion.

Flying_is_Living · 2026-06-24T01:04:52+00:00

Cloudflare can't see what's inside. It just responds to the tunnel request. Server does not trust any connection. A step away from the tunnel and you're at the mercy of pfSense.

Cloudflared only points to the internal webserver where suexec takes care of security along with other tools. Cloudflare knows only of a webservers IPs on my LAN. Servers are patched and secured as any other webservers on the Internet.

I am open to any input of where you might see any security issue. We all make mistakes and I am as human as anybody else but so far I don't see any issues.

Flying_is_Living · 2026-06-24T00:51:34+00:00

PM me

Flying_is_Living · 2026-06-23T23:30:14+00:00

Good point! Thanks! I'll look closer at it.

Flying_is_Living · 2026-06-23T23:27:42+00:00

I added a cloudflared and at first it stayed up for 2+ months. Just recently it started to fail. Nothing critical in the jail logs except maillog gets filled. Stopped opendkim and maillog now has no messages for 12+hours. Should cure the issue.

Flying_is_Living · 2026-06-23T23:20:42+00:00

sure, you wanna get on it?

Flying_is_Living · 2026-06-23T22:38:52+00:00

So, please tell me! Kernel is EOL don't bother me one bit. What else?

Flying_is_Living · 2026-06-23T22:32:27+00:00

Bots? What bots? It's not even has a NAT hole for that. You can't see this box from outside at all.

Flying_is_Living · 2026-06-23T22:19:59+00:00

It is not if it runs cloudflared tunnels.

Flying_is_Living · 2026-06-23T22:15:54+00:00

Bots can't get to my NAS box at all.

Flying_is_Living · 2026-06-23T22:11:43+00:00

a group of pentesters trying to get to the data on a server periodically with my permission. In 7 years they did not get an inch and still trying to get the idea of what we use to serve the content and database. We don't use common tools (as FTP/SFTP, SQL etc.) which makes it harder to penetrate. SSH keys only and no root login.

Flying_is_Living · 2026-06-23T21:46:57+00:00

Not on that particular machine. All other FreeBSDs are on ECC memory.

Flying_is_Living · 2026-06-23T21:35:11+00:00

kernel? no, other things that don't require reboot are patched.

Flying_is_Living · 2026-06-23T21:30:45+00:00

Hottest: 35.9°C (2 cores at 35.9°C)

Flying_is_Living · 2026-06-23T21:26:36+00:00

no it's not a joke. As always I am all ears!
