Hi all
I am totally new to this, never heard of PBX until today.
We have various rooms/buildings. In each one is a walkie talkie, we use these to call others from various places around the property. It doesn’t work great so I had an idea of setting up some kind of LAN based system as we have ethernet cables everywhere. I have also been offered a set of five new VOIP phones - Samsung ITP-5107S.
I have asked various people, and AI, I am getting mixed responses. Some say they will be able to call each other directly straight after plugging them into LAN. Others say I need a PBX system. After learning a bit about what that is, and seeing there are free PBX softwares that run on Fedora (I think anyway) - I wondered if anyone here might know anything about running a PBX on Fedora, if any software is recommended by anyone here, and if you need to be a genius to install and run it! I am not a dev by any means, but I know more about networking that most non tech people.
Any thoughts on doing this via Fedora would be appreciated. I am still not certain I actually need a PBX system at all but seems like i might so may as well try setting one up.
Thanks
That phone implements the SIP VoIP protocol apparently.
I think the ansible software is what you need.
I have no idea how have it will be set up.
Thanks. I will look that up, might try the phones first in case I don’t need any PBX software, which would be pretty cool 
Using the SIP VoIP phones, you need a PBX system.
Some popular routers in my home country have SIP/PBX functionality included (FritzBox by AVM). I am using a Fritzbox and it’s working just fine out of the box, no tinkering required, but you don’t necessarily need hardware for that.
The two software packages I am aware of are Asterisk and FreePBX. I would run FreePBX in a virtual machine.
Yes, yes its astrisk I was trying to remember, not ansible!
Why would you run it in a PBN?
I do have an old Imac which just runs CCTV monitoring software, so its on the LAN and powered up 24/7. Maybe that would work for a PBX.
I did ask someone who used to sell these particular phones and he said:
“This model can call other ones direct using IP without a PBX. Most people would run a PBX system to make things easier but if you are happy to set each handset up manually you can just enter the IP of each phone on the LAN, and make sure they all get a static IP from the router, and you should be able to assign speed dials to those IPs and call each phone from any other”
I don’t know that he is correct, i am new to this, but nice if he is
No, I was going to put Linux on it but I run iVMS-4200 software which is Mac/Windows only. if I could find a way to run that on Linux (Fedora ideally) that would be very cool! But sadly I can’t!
I ran Asterisk with multiple extensions, and multiple incoming & outgoing SIP trunks for a Minicab / Private car Hire / Taxi company over a decade ago (so memory is a bit hazy).
FreePBX (as mentioned by @augenauf) is basically the same thing but with a nice Web GUI, so if you’re more comfortable configuring things in a browser than a text editor & CLI consider that instead. Both will be more than adequate and fun to learn if you like that kind of thing.
FreeSWITCH might be another option, but has a steeper learning curve and is better suited to much higher call volumes.
