atcomsystems.ca/forum Forums VOIP Phones & IP PBX VoIP & Cloud Phones, Hosted PBX, General IP Phones VoIP Student

I am a high school student. and I am looking to forward my studies in telecom. my school has VoIP phones. The teacher had a telecom person come and talk to the class about technology. he was using terms like PRI, POTS, DIDs, SRST, ect..

I have a basic understanding that pri is a ISDN T1 connection. my question is how does it all tie together. as far as connecting pots lines to pri and setting up srst for a fail over. I know this site is not for newbies like me. I was hoping someone could help me with how all of this come together in a Voip world.

Thanks

Mike, nothing could be farther from the truth. We are happy to help people learn this industry. You'll soon find that feedback to your post will be followed by plenty of insightful advice.

By the way, you need to work on your capital letters if you want to be taken seriously by professionals. We aren't texting here.

Mike here is a good video that describes SRST. (Survivable Remote Site Telephony) Basically in a centralized call processing model where phones are registering to a cluster at the headquarters, if the sites do not have some sort of redundancy and the WAN link goes down you will not be able to process any calls. What happens with SRST is the phones register with the local IOS router and get their call processing capability from it. All the calls will go out the local H.323 or MGCP gateway & incoming calls will be handled in a way you configure. For incoming calls, I can setup DID translations for a PRI or I can route a voice-port to any extension or group of extensions.

Thanks gcave

Mike -

When you say "connecting pots lines to a pri" Are you referring to standard single line phones, dial tone circuits from a telephone company or something else?

Welcome to the board Mike - You're in good hands here. 1 recommendation would be to add as much detail as possible to your questions - That will allow us to provide accurate answers.

Also keep in mind that VoIP is a pretty nebulous umbrella. It covers things that are all over the spectrum. About the only commonality all "VoIP" shares is that it travels across TCP/IP at some point. Everything else is pot luck.

So, to reiterate brace, you need to spend a little more time doing some general research and ask questions with a more narrow focus.

, Mike. Listen to Kumba...he might be on the "darkside" (computer dude) but he does know not only his stuff but telephony also.

This is the guy to listen to, watch, and emulate.

EV607797- I apologize for not using capital letters, yes I do want to be taking seriously that is why I posted questions here for help. I understand the "texting" comment. Since I don't own a cell phone or a computer at home the only time I can post is at school. I am not a "texting" person. I will be taking an advanced Telecommunications class next year as a sophomore in high school. Telecom is what I love and I would like to make it my career. Sounds like I am not ready for you guys yet.

Thanks
Mike

Oh, i beg your pardon, why are you not ready to learn ?

Sounds like to me, you are exactly where you need to be.

Welcome aboard young sir.
