10 years later, concept still the same. Great video for beginner understanding of PBX. I will recommend this video to anyone who knows nothing about phone system and want to learn the concept.

A few quick corrections I feel I should point out. A PBX is a Private Branch Exchange, or a dedicated central office (usually around 500 to more than 1,000 extensions) that large enterprises use. A Key System is one of the smaller telephone systems used by business with less than 500 telephones. NADP = No, it's the North American Numbering Plan, or NANP. In addition, I should point out that the NANP is just the numbering format standard, and not the way calls are routed. Calls are routed using Signaling System Number 7, or SS7, which is a protocol which central offices use to communicate. They use out of band data to transmit information such as the destination number, caller ID information, et cetera. The average central office in a small town serves about 5,000 lines.

telecomguy10: Also, no phone systems are not always easy to work on. There is more than just the $600 system this guy is used too. All Dmarcs on the outside of the building? Only is someone is not doing their job. Got about halfway through, couldn't stand any more. I was curious if he knew what PBX even stood for.

rarely see information given for free anymore , your a blessing

Exactly what I needed for a new job from a repeat client! It was for a phone + networking audit/survey - I had only brief background on phone prior, this video caught me up to speed perfectly.

I must say this, this is how to teach. Clarity, aim, purpose, delivering all top notch. You are the bomb🎉🎉🎉

One hour ago I didn't understand PSTN, PBX or the separateness of voicemail. You are a master communicator Eli. Thanks very much for this lesson.

i got hired and was asked to study about "asterisk" but i had trouble understanding what PBX's and PSTN's are because no video here in youtube could explain it, was really happy to run into this class, always loved watching his contents thank you so much eli even back then when i was in college i run towards your videos for help! :)

This is the best lecturer on technologies i have ever come across.

Eli I must say that you are not only a genius but a very good teacher, very few people can explain things as you do!

Eli, I can't thank you enough for providing such a quality and insightful content for free. I was struggling for a long time to understand voice communication and then i stumbled upon your video series, and then i have been binge-watching it from then on. Once again, thanks a lot!!

10 years later. It is still relevant.

One small Comment about Trunk lines. What you describe is the operation of Analog lines, however even in the US for connecting a PBX digital Lines are more common. One of the Advantages of digital lines is that you do not have to setup huntgroups or alike with your carrier anymore. With ISDN and T1 lines a part of the bandwidth is reserved to communicate the called number, callerid, which of the connected channels the call is going to use, etc. This allows more settings to be made on site.

Hello Eli, just stop by to say thank you! I watched this video before when I'm about to take my telephony class and it gave me a jump start. Although it is not the entirety, still it help me a lot and because of it I got 3.5 in my telephony class. I think its almost 2 years ago. Now I am an engineer, so thank you and continue making up video and being passionate about it!

I'm an electrical engineer from pa. A college classmate and I started a electrical construction company and we recently ran into a telephone problem and we quickly realized in our extensive studies we knew nothing about phone system thanks to this video I was able to save the day thanks..great video

Here in 2023. Thank you very much. Quite insightful. Had to subscribe noting that I need to study alot of Telecom stuff in these two months

Don't think I have ever seen a video on technology so easily explained.Can't​ thank you enough!!

for not only these videos, i have got addicted to all your training sessions. Specially the Linux training programs which helped me to the core. More than knowledge on Linux, you have given me the confidence and made me to realize that linux is not a big deal. Thanks a ton !!

I just want to say that this was a great intro video session. Awesome job Eli! Keep doing what you are doing. You have a gift of explaining technical material in ways for others to grasp easily. Thank you.

Dear Eli I been watching some of your videos . Their extremely good. Its time I thanked you . Sir.

ELi, great video. I was forced to change careers and got 'hooked' up with a voice and data company. These videos have helped me to understand on a deeper level something i took for granted. They are also helping me to get on my feet with the new job. Keep them coming!!!

I can't even begin to tell you how helpful this video is. Thanks for posting it, I'm looking forward to watching the rest of your videos.

Thank you so much, man. I joined a company for an IT position, and being a new bee to IT Industry, i was struggling to know the SIP Trunk concept. Now I am clear, thank you for your help!

I would have to agree and say that you truly are a great teacher! I am glad I found you here, keep teaching and I will definitely keep learning, you make it very easy!

I am a network engineer and voice is like speaking latin almost, but you have made alot of the technology make sense to me and I appreciate that. Keep doing great work.

This Eli the computer guy needs tobe cloned and sent to every Technical college and uni around the world, I have learnt alot and he puts things in an easy to understand way. Good work keep on Teaching ! Now if only I can find someone as good as him to teach me Maths !

Once again Eli provides a information video that this time describes what we need to know when it come phones.

Probably the most informative and easy to comprehend computer techie site on the net. Thanks Eli for sharing your knowledge.

I thank you so much, for your wisdom and time explaining the basics for which we have learned. I'm trying to figure out how to make our small business work smoothly. We need to purchase phones without over spending. Thanks for the good work 👏

This video was SO helpful as I'm preparing to administer our Lync 2010 environement and have had no experience with the voice side of things. Thanks so much!

Eli, Keep up the great work with the tutorials on the telephone systems! Please add more!!

Great video. I was just hired at a company that has a lot of legacy gear attached to a hydro electric pump, I needed some insight to the job before I started so thank you! I know ethernet like the back of my hand but had no knowledge of phone systems

one of the great teacher on youtube.. I am biggest fan of your powerful presentation....very informative video may god bless you...

One of the best explanations of telephones systems i've heard. It's always been a mystery to me and you explain it in an easy to understand way.

Great job Eli; you have helped me a great deal. I really appreciate your teaching technique.

@xofuoy The "lines", Trunk Lines, represent how many concurrent calls that can be going on between people inside the building and phones outside the building. So if 4 people are on calls with people OUTSIDE the building when the 5th person tries to call OUT the call will fail (They may get a fast busy signal, or something else.) If on the other hand you have 6 people talking to other people INSIDE the building then when a person tries to call out they will be able to.

Your teaching skil is just awesome !! Thank you Mr Eli

You are a very good teacher, Eli. Keep up the good work. Your explanations are fantastic and easy to comprehend.

Thank you Eli! Keep helping the tech community.

Wow, Eli! You are so great at explaining this stuff! I have a new interest in business telephone systems myself and this was a great overview! I have decided to be the goto guy in my office for anything dealing with our Avaya phone system and our voicemail system.

Great class, very informative! Thank you!

Great refresher and preparation with new technology explanation for my interview tomorrow!!!

Thank you for this! Very clear explanation!

Thank you Eli Your class was/is excellent!

Dude, I learned so much in this lesson. Thanks alot!

One way to look at the PBX and Voicemail is to consider the PBX as a router, and the voice mail as an "audio server" for the system

Thank you very much Eli, it helps me a lot. Very educational video.

You are amazing! This will help many people I know!👍🏼

Thank you Eli for for taking the time to make this video. I am taking a Telecommunications and Data Cabling class in college. I am looking forward to the other classes.

For UK people, the lines coming in are normally ISDN lines, for each set of lines we would use ISDN lines, each line in has 2 channels, 1 in and one out, or 2 in or 2 out. Some use 4 ISDN in the same way.

Thank you so much. Really thank you!! this video cleared out most of my confusion related to this topic.
