Telephone System Call Routing

[@jeffz7310]

still the best 13 years later

[@ForestAdmin]

Honestly Eli, you videos are soo good. Its amazing the info you supply into your videos. You offer $1000.00 classes for free on KZbin. You are helping me impress my boss at the moment with these Telephone system videos. Thank you SOOOOO MUCH.

[@controllerbrain]

Just started working in sales at a teclo. Never sold Telco before and trying to get my head around the products. These videos are priceless for my situation. Thank you!

[@Foxstab]

Look at you, so young. Less stressed. Thanks for these tech videos. Very informative.

[@mulza]

What kind of person searches for a video on call routing, then downvotes something like this? What part of the video was worth a downvote, the call routing part? I don't get people...

[@DemonIIXII]

internet trolls

[@mulza]

fair call

[@chadb6539]

Maybe because he called people 'retarded' at 32:52, some people find that to be in poor taste or even outright rude. Or maybe just trolls?

[@robbyzoom5453]

probably kind of people not patient enough to watch the whole vid...

[@dirkpitt7857]

@@chadb6539 so true man, i cant watch this any more. my ears.

[@thomaspaterik3506]

I have over 30 years of telecomm experience. Carriers. PBXs, etc. This done well. Kudos to Eli. Your hangup of splitting PBX and Voice Mail is misdirected. Carriers want this as do large corporations. They want the ability to use the best in class PBX and the Best in Class Voicemail. One monolithic system means they have to compromise and select one vendor that has much of the features they want. I have had so many bidding and evaluation projects, that this is standard practice.

[@igenr8]

These three videos have been wonderful. I am shopping for an IP PBX and these videos are helping me make tax more informed decision.

[@madezra64]

I'm a Network Administrator BECAUSE of Eli. I owe this man my lfie.

[@lavish2102]

I am new to the Telecom field & wanted to learn about call routing, Watching this in 2020, very good video.

[@Samlol23_drrich]

Thank you very much. I’m a dentist who likes to know how the stuff I purchase works so I can at least modify it myself if need be. About 10 years ago I purchased a new NEC phone system which the sales group programmed. I got hold of the manual and it’s 1000 pages of what might as well be Chinese. There is really no info anywhere on the basics. When some displays started to go blank last week I decided to take an interest again. Who knew there was a cr2032 inside; not me. Well anyway here I am with the first real basic understanding of what was set up for my office. Thank you again.

[@MBilalabdulkany]

Listening in 2019. Well explained and best video out there!

[@radianttelecomms]

yes, this is very important, what a good time i have spent watching this elaborative video. Surely Eli you have helped me

[@plinio_cruz]

Eli, thanks for sharing technical knowledge straightforwardly. Plínio from Brazil, 2020.

[@stephenkojovan8634]

We little guys and African...rarely get this information....thanks sir...

[@chrisgast]

I wondered how the calls to my help desk handled. Thanks for the info.

[@Tysio100]

"If you need a life press 3!!" xD

[@mythilyponnappan]

Brilliant..!! Easy for anybody to understand the basics.

[@nazaninrezvani4668]

Thank you.U explain in a simple way

[@aaronwilson4215]

"If you need a life press 3" 😂. Great info!

[@michaelcostello6991]

This was very helpful as an introduction to this technology. Thank you

[@coreyowen8864]

Comedy Genius and Technical Genius. Hopefully one day I can be both too.

[@MouadEchchaaba]

Hi Eli the Computer Guy , Thank you a lot for your simple and clear explanation. I think thay youtube should add a multiple likes system to your videos so we can make as many likes as we want :) From Morocco.

[@darthorpheus]

Building my IP PBX with Bluebox using Freeswitch. Thanks for helping me better understand.

[@dnb5661]

Intercom is a line that goes from the PBX to the station. Paging system is what you are referring to when you say "intercom system".

[@rybaluc]

Analog phone line voice is not modulated onto carrier wave, therefore there is no carrier wave. Its only electric wave created and directly modulated by microphone with some additional circuitry like echo cancelation and audio equalization. Carrier wave was used together or simple frequency multiplexing back in the old days for analog coax cable phone trunks.

[@datashed]

Very useful in helping me set up my home PBX, a Merlin Legend. Yes, I'm that crazy.

[@rybaluc]

PBX could be virtual or it can be located in customer premises but managed remotely by your telco. You have just normal phone lines to office/offices, but you can control line configuration/routing/mailboxes from some web application.

[@drmonica]

great vid on call routing and auto attendant

[@brandonfarfan1978]

Super informative lesson. I learned alot in this lesson. Thanks Mr. Eli.👍

[@kd1s]

Lots of experience with phone systems - dialplans, ars, etc.

[@j0e14]

you're the best ELI

[@kaktotak547]

Awesome explanation! God bless you!

[@marksatterfield]

hey thanks for these videos -- yeah, a few years late, but I think you've done a great job Eli.

[@namsubatman2705]

I love you so much ... Helped my job immensely

[@amberyu7976]

Thank you so much for all these information. That helps me so much on my work!!!

[@imranrashid367]

Hi..... Eli Brother i really really happy to found along with PBX nice and easy understand basic knowledge lecture. Thanks for your Efforts and help to share your collected knowledge about this topic and it world.

[@fstemarie]

Try Elastix. It`s Open Source software based on Asterisk. Install it in a VM (with Virtualbox or any other virtualizer). You can use clients like Qutecom or any VoIP client to practice but soon enough, you`ll want an FXO/FXS like the Linksys SPA-2102 to use you main line as an extension ;-)

[@dharmen4oracle]

hey eli, in the Introduction to Telephony you told their will me lot more videos for us to learn the whole Phone system in depth. After introduction, i saw your Introduction to Voip and Call routing clas.. Is their any other video related to this topic. I'm unable to find any. Please lemme know

[@ezzadinhausawi5813]

You are ginus bro, you make ordinary people act like gorgeous, thanks a lot boss 🌹🌹 But I am confused about PBX and voice mail are they in the same box or different devices?

[@davidwise9119]

Asterisk is a free, open-source software-based PBX. There's an article at Wikipedia.

[@mohammedwudood2823]

cool and simple explain way ... thanks

[@rybaluc]

NADP is not routing itself. In USA this is done via SS7 inside phone network. Other countries can use many other standards. Voice and signalling is handled separatedly and by different ways(i mean trunks) between central offices. NADP its only logical assigment to physical areas. Routing itself can change from call to call and depends on many factors like network load, outages, prices of central offices trunks (sometimes satellite to Bahama islands cheaper;) than fiber optics).

[@TheSword3000]

Your vids are the best! Thank u!

[@gairdian360]

Thanks for Uncomplicated!!! You Rock!!!

[@allenyu6678]

very clear explaination !

[@lloydtripp3793]

Thanks for the speedy reply! I'll take a look at that.

[@DavidSomersHarris]

So are the separate functions of the PBX and voice mall system the reason why you used to not be able to press your number for the auto attendant until after the tone? And how come many systems support this now? Is it because of VoIP?

[@frederickafrihyia6256]

Hi! thanks so much for this videos

This is really well explained,thank you!!

[@tanyagrigoryeva1260]

Well explained !!!

[@RideAcrossTheRiver]

Why did I suddenly get 'All Trunks Busy' tone one night at 12:00 AM? Only intermittent dial tone since.

[@rozminalakada6779]

Eli, if call groups are just systems in which call gets routed to everyone in the area/instituion, why wouldn't most people use them? are they costly. what are the cons of using them?

[@carpediem8807]

Hello. Can you please explain me about trunks. You said - If I have one trunk, this trunk must have phone number and if that trunk busy nobody can call. But how the whole company can call with one callerID number? Each of that calls takes his trunk with the same phone number as the rest of the trunks?

[@8118is8]

Thank You so much Eli.

[@binman20]

Thanks, Eli.

[@cleatrampler]

Rotary phones are neither stupid or little. Most of my phones are rotary. However, with Asterisk, a TI card and a channel bank a rotary phone is as fast as touch tone.

[@algnadjib]

thank you so much very very helpful info

[@AhmedTouma]

Thank u so much from Egypt

[@Poruntz]

Is call path same as hunt group? base on the explanation they are alike? Thanks for the video! keep them comin!

[@Alihubail19]

Thank u very much it was so helpful

[@toosinbeymen6304]

QUESTION: If you program an outcall to a number in an office that has extensions, will it go directly to the extension? Or will it have to go thru the receptionist/autoattendant? What does that look like? is it 212-555-1212x222? or some other format?

[@gimposer]

Amazing video... thanks a million..

[@roleric]

Great!! this video was very helpful to understand call routing. but I have a question... Is there any difference between IVR and AA? thanks for uploading this videos

[@abhinavgoel815]

Hello, I was hoping to make a telephone routing system of my own as a side project to my main college major. I use an Arduino for most of my projects. But i am having a problem converting the Analog signal coming into my land line into digital pulses. Can you provide some assistance on that front? It would be great! Thank you!

[@charchabal35]

Jut the Best still in 2021

[@riribichri4087]

Is the call path you explained at the beginning and hunt groups the same thing?

[@cyberpunkworld]

Look at all of the modules... Which of them transmit?? Which of them receive. So there's trasmission/receival over internet and normal telephony. I want the normal telephony modules only!, on the server-side, and I want internet capability on the client side-only... With some minor detail modifications which you are to work out ;;;)

[@rybaluc]

Trunk line can contain many phone lines inside contrary to you said that trunk=one call. But i admit that terminology can differ if you trunk line means technology type of interconnect from central office (like ISDN-PRI) to your PBX or logical identificator of one voice call possible to your PBX by some technology. Trunk is not a trunk;)

[@jcl410]

I know I'm replying to a 5 year old comment but ..... The "trunk line" terminology in telephone systems has remained constant since the beginning; where every single call went over a single twisted pair as analog. So; a "trunk line" carries one call between two phone switches (to include Private Branch eXtension switches) A T-1 (DS1) contains up to 24 DS0 trunks. It's normal to assign those 24 trunks to the same trunk group. If you have ISDN-PRI service, you'll get 23 trunks (bearer channels) plus 1 data channel (for signaling to the up stream switch.)

[@linuxxxunil]

So all the programming is done with a telephone handset ?

[@MrLuvusi]

Wonderful videos..thanks alot

Thank you!! This is really helpful!!

[@elithecomputerguy]

PBX no... VoIP Servers... a whole bunch... take a look at the free version of Switchvox...

[@MultiBigchad]

Eli the Computer Guy how do I get more calls routed to my extension without contacting management. When someone calls and push 1 for new sale I want a high probability of receiving that call

[@NetworkEngineer]

If you need a life press 3. Classic!

[@krishanakhatri4603]

What a legend.

[@mohamedaziz5340]

thanks for the explaination

[@Oldgoat38]

Again, thanks so much.

[@picabodaddy]

Can a trunk line be part of multible trunk groups? Also love the videos. Thanks.

[@rybaluc]

Digital vs analog ports on PBX - It depends. This is only true for stupid simple PBXes. But some systems can use one physical port as analog and digital together(its possible to separate them due different frequency bands and save some copper) or configure some ports as digital or analog. You have also those proprietary phone systems like Nortel which have no standard ISDN digital line but some of their "digital line".

[@banugaria967]

could you please make video on ULL, or give brief info please

[@rafalpilat145]

thank you! great tutorial

[@rybaluc]

Phone company is not always responsible for network itself if you are using someone else network through their network. If you are using different operator by prefix or gateway to non public phone network, then companies which owns cables are different from companies providing phone services and also different phone companies providing custom calls trough special prefixes or numbers. You need to know who provides which services.

[@alibalnuor2818]

you are the man

[@mcherem]

Great Stuff !! thanks

[@lloydtripp3793]

Are there any PBX simulators that are free? I'd like to setup a telephone network to just see how everything looks logically.

[@AliAlHabsiAA]

Learned a lot. Thanks Eli. :-)

[@ibrarmushtaq2430]

Hello, eli can I ask u something please if u don't mind In year 2003 i used to work in telephone company, I rang my brother from office landline number and shows mobile number on his mobile phone it was really weird because I actually rang from office landline number is that possible ? Could it be technology fault? When my brother rang mobile number it's like does not exist doesn't ring or go through voicemail Please reply asap Many thanks eli Iv subscribed

[@angelmanuel6826]

what's up. I'm looking to connect to Branches in different states, one systems is a nec aspire and the other is Avaya, the NEC in on my site. what do I need to have in my nec in order to connect to other office?

[@footiecyclo]

Thank you!!!

[@DaaniaShahid_1084]

it would be more helpful if u demonstrate using PBX devices

[@pepe6666]

i thought a trunk was actually a line between exchanges/central officies. the line that goes to ya house is a subscriber line right?

[@DemonIIXII]

a trunk is simply the communication pathway. with trunking it doesnt have to be phone lines that connects directly to the PSTN directly to your home/biz, it can be an ISP. i think youre reading to far into DSL digital subscriber line and then adding/mixing it with "phone line".

[@jerichojon]

Is call path and hunt group basically the same thing?

[@suryawbs]

Hi Eli! I tried to access the video and see a “no stream” notification. Just want to clarify whether the video got deactivated for the time being? Thanks!

[@elithecomputerguy]

... works fine for me... maybe just a YT quirk...

[@apirtayogame]

I SO REALLY NEED TO PRESS 3 hahahaha

[@MrFouex]

excellent...

[@RammyBrad]

thanks man!

[@DavidsKids219]

Eli , how can I get my avaya PBX to be able to dial internationaly?

[@erosveizi91]

How is international telephony traffic routed??

[@jeffersota]

I want trunk group three to route to "the Bordello of Blood"

[@fttx]

32:46 😂😂😂😂😂😂

[@gregory-michaelsheen9292]

Where / how do you actually programme these paths into the telephone system?

[@moopo923]

In own software of Nortel,Siemens, Panasonic like
