Hi Eli, I am very thankful of your videos. Because of you I got a job in servers. I did not have even the basis idea about networking, servers, protocols, and how things work in business. but you made it so easy for me to understand all the things. I stated watching your worthy videos from last 6 months. I started from basic and keep moving forward. I acquire great knowledge from your videos. At the starting days of interviews, I got the rejection at that early time. But I did not give up and kept trying. Then Finally I got my desire job. the best thing about your videos is that you start from basic terms step bt step and correlate it with practical things which happens in business industries which makes it very simple to understand and it also create interest in learning. And then you take it to the advance level from intermediate from basic and then at the and of the video whatever you described that settle down in our mind. I really like your videos. And this is not the single quality what i found. If i talk about the way you describe, talk, communication with the viewer and a little bit humor as well. Thank you once again for sharing the videos on youtube and your videos did a great job for me.
You must be a great learner Ayush. Over the 23 years of my own experience I can definitely confirm to you that yours is a rare breed of student. Keep your mind open and keep learning. A man stays in students phase throughout his life and has it's great pleasure in it.. connect with me on fb Sandeep if possible.. would like to have peoples like you in my friend circle. m.facebook.com/profile.php?id=100000476180981 don't forget to mention this thread. :-)
@@Niche_skills He didn't really say what the job is he's doing right now. If you work with windows servers gui it's probably gonna be a bit easier than doing everything with terminal or unix like systems (depends what you're used to anyway. Maybe Windows is harde to understand because you used Mac all your life?). But ofcourse basics like Ip's, Masking, DNS and DHCP (which technically isn't required in a network but it does makes things far more easier for you) and various security options are as good as being used everywhere. So yeah it's hard to say. If it is indeed what he's working with right now it wouldn't be so hard to imagine that you could land a job with it. Especially if you create your own roads, started with this type of videos. A good dose of passion is also necessary ofcourse or you'll stop learning and eventually fall behind.
In all of my 4years working in the IT world, I have never met or heard anyone explain and break this down in such clear and kind manner. Thank you Eli. I'm so grateful I stumbled upon this today. I know I'm 9years too late but this still very much applies to the job i'm eyeing for now. Thank you so very much!!! God bless you.
I'm extremely impressed with how articulate you are and your Ability to communicate complex language to a lay person. I now feel confident in speaking to VoIP companies with full comprehension. You're awesome :-) Thank You Eli
Eli ... I am charged with working with a vendor to implement a VoIP phone system for our small company. Your video was extraordinarily helpful in giving me a basic understanding as I start this project. Great video .. if things have changed much since 2011, you may want to consider re-recording .. but, I'm sure that many of the comments are the same. Thank you ...
After I watched this video all I can say Wow. I have never heard anyone to explain something complicate in so simple way. Thank you for sharing your knowledge with us
Прави ми впечатление бързо реагиране на нещата ...С удоволствие приемам новата форма на контакт. Ви сте невероятни "експериментатори"! Thank! Бог да Ви благослови!
Thank you Eli. I am learning for my CCNA Voice exam and I was looking for a high view explanation. My wife came into my room and spent about 10 minutes watching your video and was surprised and amazed that she can understand everything. :)
Man...i am an Telecomms and internet engineer having an MsC...u are just perfect...you explain everything really from scratch....thank u for remind me all my basic knowledge and not only basic.... :)
I work for one of the larger Technology companies, which I will not name, :) and i've learned more about VOIP and SIP watching your videos in two days then in my three years and all the trainings combined. ha! you have a skill of breaking it down so anyone can learn it. Well done. Thanks for posting these video's.

I came to this video hoping for info on VoIP and SIP. I saw the timestamp, and I was hesitant. But somehow, inexplicably, just about all of what was said here is still relevant in the madhouse that is 2020. Well done, Eli. Well done.
Why? I set up a dial-operated telephone to work with my router. I love old technology. It's much more charming, easier to fix and in many cases safer (less EMF radiation, harder to breach), too. That digital craze is stupid and environmentally quenstionable (think power hunger) in my eyes. A normal landline is much more robust than an internet-powered telephone (think power outages, router failures, IP-leasing issues etc.; Unfortunately, I cannot afford an additional landline, so I am stuck with my VoIP solution.)
Brilliant Eli! I am starting a new career in telecoms after working in advertising and marketing for 12 years. Thank you for sharing this information with us dummies!!! John
Whatever topic I search to learn in IT world, you have already prepared very nice and easy to understand videos about it. Just wanted to express my appreciation for all the passion and effort you put in sharing your knowledge. All the best man !!!!!!!!!!!!!
Fone Star -- VOIP doesn't suck! Yes, there are some crappy VOIP phones out there. (There are also some excellent ones.) I run several mid-sized businesses on VOIP. I can accomplish now for literally PENNIES what used to cost an arm and a leg. We no longer even think about "per minute charges" for our call centers. I can distribute personnel however I see fit around the globe without issue. Call quality is generally much better than I was getting thanks to great codecs like g722. Conference calls are a breeze. I could NEVER go back to antiquated old systems like Panasonic, Nortel and the like. I've built many Asterisk solutions for "hundreds of bucks" that completely outperform systems that cost tens of thousands of dollars. Seems like a lot of old "phone pros" feel intimidated by VOIP and Asterisk... Don't. Learn Asterisk. Your clients will love you and your bank account will grow.
Awesome, thank you. Just joined a communications firm in telephony sales and your videos are helping me stay afloat and learn all the new terminology and concepts.
Eli, you are one of the most reliable and quality consistent "Go To" reference providers that I (as a noob) have had the pleasure of utilizing to date!!!!
I know this video has been kicking around for some years now and the many others made have led to a new path /position for Eli. Just want to say well done you and take note anyone that knows something worth sharing, make an effort, break it down & open the door for others to learn. This video and plenty more self learning references helped me understand voice and data. Taking the time to consolidate and share the things you learn with others, to help them get out the blocks,is a great thing. I rarely comment on videos but now appreciate that sharing is caring!
TCP does not provide any security at all, just like UDP. TCP gurantees the order and delivery of the data that you're sending, whereas UDP does not. This makes TCP a lot slower and if the data doesn't arrive, it has to resend until it arrives, which can create delays in VOIP. So UDP is much desired over TCP when it comes to VOIP.
I am starting in a new IT company that does UC or UCaaS as some would put it. I am relatively new to IT, and i find your video very informative. I am going to be very popular in sales, because of your videos.... Make me Rich Eli, Make me Rich.
Eli is pronouncing it correctly! 99% of people can not tell the diference between Internet (eee)nternet & our tech jargon of Ether-net. (bEth). A Word has the priority to convey a Meaning, not gramaticaly correct literature pronounciation.
Awesome explanation ! Don't worry about people who complain about the video being lengthy - I am grateful for your knowledge share and time you invest in making such videos !
You are a genius man, yo motivated me to get into VoIP for the first time, and i'm just a UNIX SA! good work on the dynamics of the video and the clarity of language and explaining
Thank you for your excellent explanations, for your pristine audio recording and for your impecable diction and pronunciation. For a non native english speaking guy like me, that is the great difference between the possibility of understand everything you say or understand nothing and look elsewhere. Kind regards.
Okay, I have to say that I have been watching video after video after video for the past couple of days. You make the complex seem simple and very easy to understand. You, my friend, are incredible.
Hi Eli! I am also going to go for an interview tmrw for network and I UNDERSTOOD ABSOLUTELY NOTHING BEFORE I STARTED TO VIEW YOUR VIDEOS SO THANKKK YOUUU SO MUCH! This was great, concise and your passion really shines through! It made a possibly dry subject interesting and easy to understand!
Thank you Eli your tutorials are much appreciated. Helping me understand all the concepts for my diploma in networking class. I started at 0 and am much more aware and switched on because of your videos. Thank you.
Really worth to spend 1 hour for your VOIP learning, thanks very much Eli good effort. I never comment for anyone bcs I am lazy to type, after hearing this I want to comment and thank you
yep... it's the total number of calls occuring with the OUTSIDE world. So 2 incoming calls, and 2 outgoing calls would use 4 trunk lines. You could have 2 incoming calls, 2 outgoing calls, and 8 internal calls going on at the same time because the calls between extensions do not use the trunk lines.
Thank you so much for your videos.i am learning VoIP by your videos.Your way of teaching is excellent even a baby could understand.Please continue posting more videos in VoIP.Thanks
i can't believe that after 6 years, i am now into this kind of technology! and a heartfelt thank you for you, Eli! i love you man! :) you are the ideal trainer I am looking for!
LOL I loved Eli's ediot ratios. Great video, my job responsibilities are veering into phone support in our organization. Your videos have been great in getting me caught up so I can have an intelligent conversation with our vendor.
Thank you Eli your tutorials are much appreciated. Your videos has helped me since the very beginning of your channel. I watched this VOIP video today since I have an upcoming interview few days later. The way you describe and impart knowledge is absolutely commendable. If I ever get a chance, I would love to be your acolyte.
Found this really helpful, I've just started working as an apprentice for a telecommunications company and this helped my understanding a lot! I've subscribed and will be watching more of your videos. Thank you very much!
Hey Eli, Thanks for the precise and informative introduction of VoIP and all of the features associated with it. I am a VoIP service provider and love to dig more informative material like you provided in your video. Thanks again.
Eli you are brilliant teacher! It's a pity that I discovered your videos only today. They could have saved me tons of hours spent on reading. Thank you very much from Russia! P.S. Your beard is cool.
Eli u r the best person i have ever seen... Posting video selflessly hates up to you... Thanks very much... Running out of words for thanking you... Thx again
Eli....That was a fantastic class on VoIP communications. The codecs was a bit confusing but I think I got the jist of it. I have noticed that CompTIA and other cert programs go over VoIP, but it is not this intensive and clarified. Basically, this class cleared up all my questions on the VoIP operations. Thanks for posting this class. Top accolades, Eli.
I love your videos. I just came across this video while researching for a informative speech on VoIP. I will definitely be watching more of your videos. The way you explain things is so down to earth. I love it!!
Thanks sir for the very clear lesson. I was really unsure if i needed another network device to add it in my network design for inside the office. I clicked the advertisement.. you deserve it.
Wao! Very clear! awesome, simplified explanation... Eli, you are born to explain things! Thank you man! I tried to get to understand the VOIP for office, but all our connections could or would not explain it! Now I know why! A Brilliant presentation, short- direct and to the point. Thanks!
Goes out to the PSTN (public switch telephone network.) important to specify that. Also, important for the student to understand the concept: in that VoIP, we are taking voice transmission (communication,) which is analog in nature, and converting that signal into data "packets." This provides the ability to carry voice communication over the network in conjunction with data transmission of the network itself. Carry on...
Excellent; and thank you for making the subject so easy to understand. For quite some time I really needed to understand the basics for VoIP mechanism and tried other references including vedio from others on youtube but this was the one I found what I needed. Please keep up good work. Look forward to your other vedios...best wishes. Anup, New Delhi, India.
Eli, to be honest don't have no words for you man, you are just demystifying like you said man and you REALLY ARE, i don't know what to say man, Thank you a million... I subscribed, i gave a thumb up to videos that I've already seen....

This is great!!.Am now becoming a Voip gulu
Still watching this video and not over, I'm amazed by the way you present concepts. You are tremendous.

It's sad when you watch this in 2019 and you are still using technology that Eli refers to as "in the old days".
Why? I set up a dial-operated telephone to work with my router. I love old technology. It's much more charming, easier to fix and in many cases safer (less EMF radiation, harder to breach), too.

VOIP uses the UDP protocol instead of just TCP. Using TCP would be too slow for real-time voice.
you are wrong
yes ..Use of UDP is good than TCP...
You can't use TCP to real time live services
Saiga S UDP provides speed but not reliable security which is the opposite of the TCP wherein a little bit slower but more reliable in security.
TCP does not provide any security at all, just like UDP. TCP gurantees the order and delivery of the data that you're sending, whereas UDP does not. This makes TCP a lot slower and if the data doesn't arrive, it has to resend until it arrives, which can create delays in VOIP. So UDP is much desired over TCP when it comes to VOIP.
I am watching this video 9 years after it was published. Very informative, thank you so much!

yep... it's the total number of calls occuring with the OUTSIDE world. So 2 incoming calls, and 2 outgoing calls would use 4 trunk lines.
You could have 2 incoming calls, 2 outgoing calls, and 8 internal calls going on at the same time because the calls between extensions do not use the trunk lines.

Appreciate the multiple reviews and summaries of previous material as you start new topics - it helps!

Anything,
Eli....That was a fantastic class on VoIP communications. The codecs was a bit confusing but I think I got the jist of it. I have noticed that CompTIA and other cert programs go over VoIP, but it is not this intensive and clarified. Basically, this class cleared up all my questions on the VoIP operations. Thanks for posting this class. Top accolades, Eli.
I love your videos. I just came across this video while researching for a informative speech on VoIP. I will definitely be watching more of your videos. The way you explain things is so down to earth. I love it!!
Eli is really good isn't he? I have been going through his videos to better explain concepts and brush up on interview explanations etc.
Thanks sir for the very clear lesson. I was really unsure if i needed another network device to add it in my network design for inside the office.
I clicked the advertisement.. you deserve it.
I usually get kind off depressions when i need to understand stuff like this from english tutorials etc... But Thank YOU Man.. Subscribed ;)
I took a few ATA's and unlocked them for my business and used open source sip and google voice and I have a nice free setup :) thanks for the video
Wao! Very clear! awesome, simplified explanation... Eli, you are born to explain things!
Thank you man! I tried to get to understand the VOIP for office, but all our connections could or would not explain it!
Now I know why!
A Brilliant presentation, short- direct and to the point. Thanks!
I was overwhelmed before I watched this. Thank you!
Firstly appreciating the very informative session then it was best at 44:14 to 44:18, that's so accurate.
😁😁😁
I just wanted to say thanks for making this video, very easy to follow. I'm just getting into the communications field and you've been a real help.
Excellent Job Eli! Don't change a thing - it was perfect!
I just wanted to thank you for taking the time to make these videos.
Eli is the best of the best. The guy knows his thing!
Man, you are my favourite on Internet.
Thanks for these awesome videos.
Goes out to the PSTN (public switch telephone network.) important to specify that. Also, important for the student to understand the concept: in that VoIP, we are taking voice transmission (communication,) which is analog in nature, and converting that signal into data "packets." This provides the ability to carry voice communication over the network in conjunction with data transmission of the network itself. Carry on...
Excellent; and thank you for making the subject so easy to understand. For quite some time I really needed to understand the basics for VoIP mechanism and tried other references including vedio from others on youtube but this was the one I found what I needed. Please keep up good work. Look forward to your other vedios...best wishes. Anup, New Delhi, India.
