We need phones, a PBX, and networking equipment. Let's go over some hardware we can use, and the hardware that I use in my own system.
A big myth I would like to shatter here is that a PBX has to be "expensive." Yes, setups that can deal with 10,000 users are "expensive", however, I assure you - the people telling you PBX servers are expensive are often people who themselves are selling you something that costs even more. :-)

I'm using a Raspberry Pi 3B+ running RasPBX, which is even less than your $80 Lenovo. There's a beta RasPBX for the Raspberry Pi 4B which will handle even heavier loads. I've got four DIDs on going to three phones, one of which is a ten line cordless. It can bog down if it's doing a complete system backup, but otherwise it's quite good - so backups are scheduled in the middle of the night. I anticipate the RasPBX on a Pi 4B will handle an even heavier load. More than enough for a SOHO with a handful of users and a system that doesn't have an exotic menu system attendant with redirect options - multiple DIDs resolves much of that - and the DID provider is dirt cheap. The best part is the exceptionally low power consumption which would show up on a home power bill - I've left a desktop PC running 24/7 and it shows. The one thing I'm not saddled with is heavy LAN use with the occasional streaming movie use - but not more than one going at a time. I agree regarding switches and have been using Netgear Prosafe 10/100/1000 unmanaged switches. They have been quite good and are less than the Cisco. A gigabit LAN is essential. The phones are Grandstream and I've had no problem with them. At their low prices, they're still the most expensive part of the system! At this point I'm integrating a FXS POTS line and another FXS cable provider line (which terminates in an FXS port with a gateway built into the cable modem) into the PBX. The AT&T POTS line will be the 911 local access - adding three more PSTN two-line phones onto the network (on a common 4-wire PSTN cable). Bottom line is it's possible to go with even less if the load isn't heavy. RasPBX has been incredibly reliable. Just about runs itself unless I start recording phone calls and must manage the recordings - even with a CRON job that will delete recordings after they're over 6 months old.
Hey Louis, sorry but I have to correct you with two things. First: You don’t need a switch with QoS. The bottleneck isn’t the switch, where you have to prioritize the traffic. You are going to need a QoS Switch in a really big network with stacked switches, and so on. And in this setup you gonna buy managed switches, because some thousands of $$ doesn’t matter anymore. In a usual setup, (with running Backups) you just need a switch with a great backbone. But back to the Backups. The bottleneck in offsite backups is not the switch, it’s the Internet Connection. So your Router has to do QoS, not your Switch. The Switch just has to be able to keep the QoS Header in the Packet.
Second thing is, that Cisco is not Cisco. Real Cisco products runs the Cisco IOS operating system. The switch you showed in the video is made by Cisco S(mall)B(business). As you know, Linksys is a devision of Cisco. And Cisco SB is like Linksys in Product Quality. Even Cisco SB Products are good, but Cisco SB isn’t Cisco.
+port29dr still beats those $25 pos switches I am used to seeing in small offices that call to ask why their stuff doesn't work
+port29dr I do have the same opinion, the router has to do the QoS management properly.About brands im happy using mikrotik..
+port29dr Thanks for the extra info (didn't know about Cisco SB). Louis' point of "don't use Walmart Special hardware" is well made, but its good to know this info too. One question though, you mentioned managed switches in big networks, but for a small businesses' PBX running on a $300 server, an unmanaged switch will work fine?
+Krynn72 That’s kind a question, I can’t answer with yes or no. I know small businesses, that are using a crappy 15$ TP-Link switch and are fine with that. But the problem is, that they are limited in what they do. But they are fine with that. But if you have some issue with the network, you can’t do any analysis.
My personal opinion is, that you need a managed switch, if you run a business. The price difference between a new unmanaged or a smart or managed switch isn’t that great. A good quality switch is going to work for about 15 Years. So if you pay 300$ for a managed switch, it’s just 20$ per year. It’s nothing. Especially if you are able to save taxes with it. If you can’t afford to buy a brand new 300$ switch, you can get a used one for 50-70$ on ebay.
Hello Louis! Thank you for posting this VoiP phone video series. Is it possible to consolidate this series into a single / searchable playlist so viewers can seamlessly transition between videos? Right now viewers have to search for the next video without knowing the title or anything, we just hope that youtube's algorithm selects the next video as an option and presents it in the 'related to' section.
In the spirit of affordability and keeping things more under your control I'd like to mention pfSense as an alternative for a Cisco managed switch. You can buy relatively inexpensive hardware and add Ethernet NICs as you go along.
you are the man brother
There are cheap quad core fanless boxes on eBay that has more than enough CPU to run FreePBX just fine. They use around 10W or so..
Louis thanks for the video. I have another question. Let's say you have cable at home. Do you call your ISP and have them turn your service in to bridge mode so you can have a better control?
Do you still recommend the Cisco SPA525G as the phone to buy in late 2017? Also, is there a softphone that you recommend for testing the setup if you don't have a IP Phone yet? Thanks--the tutorials helped a lot!
Thank you!!
hi louis,thank you so much for this tutorial, i have set up a freebx server, i have 4 phone set up, i'm wondering, what sip trunk provider you would recommend , i am looking to make a lot of outbound calls in the US.,Do know of any unlimited sip trunk providers? Thanks again.
informative. A couple of flaws. There are use cases for QoS. You should always use managed switches in a business. Unmanged switches are really for home use or a one man operation. How else do you stop people from plugging in unwanted devices? You can also use a switch to manage traffic and bandwidth thresholds on ports. Old hp switches cab do this if find the right one.

Thanks for the information
Hello Louis, I own a phone now thanks to you I know how to ring people now I’m working on a system in which I can leave the house with my Cisco ip phone but I’m having some trouble. any recommendations?
As far as QoS can't you adjust that in the router settings even if it was cheap? Why is it necessary to buy a more expensive switch?
Great video as always. have similar problem. I have Avaya ip Phones but not with Avaya pbx. Will this kind of setup work for Avaya phones . Please let me know. Thanks
I did see your videos are very detail and interesting.I am new in this, so I have a question. I do have a Free PBX already, but I want to integrate a phone in but it is in other location. the question is. ... do I have to get a server also in the new location or as long that I have internet connection it will work by connecting of adding the phone in my Free PBX with a asterisk as a GUI.I appreciate your help.Thank you
What ports in the switch do you suggest to connect the PBX server, the phone and your line cards(PRI or ISDN? Or any port will work?
hi. nice video. any new suggestions on hardware since this is 2 years old?
What setup would you recommend for a very simple IVR (almost an Auto Attendant) for one single landline?
(caller interaction via keypad, pre-recorded messages, calls must be recorded, static menu, no call routing, ...)
You could do all of that with FreePBX and Asterisk running on a lowly Raspberry Pi 3B+. It's called RaspPBX. I've got four DIDs with SIPs running in my home on multiple line phones. I'm about to integrate the POTS line and a cable company FXS line, which terminates on the cable modem in an FXS connection (cable modem uses an internal FXO to FXS gateway as Joe Consumer has PSTN phones). That will require an FXS to FXO gateway. It will give me six phone numbers on the PBX. Been using it for about a year. If that little itty-bitty box and its ARM processor can handle what I'm doing, it can assuredly handle what you're looking for. The kicker is wanting your calls recorded. That will require something with the capacity to store them. You would have to manage the download for long-term archival storage depending on how long you need to maintain them. If not for that you might be able to use a simple FXO-FXS gateway box.
Hey I wonder if you have ever tried DD-Wrt? I use it at home and it seems to provide a decent QOS. I have Two Bridged routers, but have Set a Virtual LAN on the 4th port of the first router With a DCHP SERVER(2.2.2.1). The first router (1.2.3.1), with Wifi enabled for me and my Wife's PC's (One Net), The DD-WRT Virtual Lan manages the virtual LAN on the 4th Port. The Second Router(2.2.2.2) is just in bridge connection to The 4th port of my first router. This Router is sharing WiFi(guestnet) to guests and has a bunch of computers I use for torrenting n tests n projects. This way my critical pc's are inside the Their own LAN on the first router. and The others are stuck on the Virtual Lan. I use a the simple port QOS on my first router to keep priority for ports 1-3.and this is working nicely. There is no bridge to the first router sono one can see or connect across to the other network. thusly busy activity on the guest side and a noiseless quiet LAN that has priority over the other. you could do more QOS if you wanted...

also as a sidenote to your Linksys shaming, Cisco bought Linksys and it's branded now as Cisco aswell (Cisco Small Business 100, 200, 300 series = former Linksys). If you want "real" Cisco, then you must choose Catalyst, which is sadly crazy expensive :D
Has anyone tried using something like the AWOW mini computer with 2 LAN ports (Amazon, $200) for a phone system server? Comes with some sort of SSD built-in, but it looks like there is room for a 2.5" as well. I need to set up an office system with 8 phones and have a small space for a server... can't fit a full-size box. Any help would be much appreciated!
You can run Asterisk on cheap piece of crap router. This is exacly what is running on most GPON routers.
im an ignorant....why use a new harddrive as opposed to a wiped used one?
because you are an ignorant
@@alexandroskourtis5268 My ignorance cannot be the main reason for using a new hardrive. They are completely different things annd do not affect each other. A hardrive is a physical object whose active compnents are made out of either semiconductor or magnetic materials which can be used to store binary data. Ignorance is an abstract concept that applies to sapient humans that marks a lack of knowledge in a specific area that may be considered general or common knowledge. For, example not knowing that being an ignorant does not affect whether one choses a new harddrive vs a wiped old one is itself a mark of someone being ignorant. Do you understand?
@@larsongregory2330 lol k.. U obviously know i was joking but u decided to fuk my brain up either way
@@larsongregory2330 your first question is valid... Its just that i found it funny the way you wrote it
@@larsongregory2330 lololol im still laughing with ur response lol
Where is part 4?
+BoxTech Whoops - thanks for that! part 4 is out
Thanks :)
+Louis Rossmann Part 4 isn't on the playlist :P
Has anyone tried using a Raspberry Pi 3 as a PBX server?
Jackie Godinez yeah, worked just fine with about 10 IP extensions and SIP trunks. It was just an experiment, but we ended up using it at the office for a couple of months. Why I wouldn't recommend implementing it even semi seriously, is the SD card and its power adaptor, because both of those things tend to go to shit.
Update... I've now been using the Raspberry PI 3 as my main PBX server for my small business for about a year now and its been solid as hell. Fingers crossed.
