Web Hosting Talk : Web Hosting Main Forums : Specialty Hosting and Markets : VOIP etc : Your own voip ? making calls ? gateways ? ahhh dont even know where to start ...

[prixone]

hi,

i am a very curious person about how does the voip works ...

so far i have learned many things but still not enough to know ...

if you made your own server lets say using asterix or any other resource avaliable and want to call to usa or japan or anywhere what is your first step ?

Basicly do you have to have a contract with at least 1 telecom from that country in order to be able to make calls to them ?

How does it work at all ?

Thanks in advance for any little reply to fill the blank spaces in my mind ... and also to create new blank spaces that i will be coming back to post

I like the comment about how being a marketing genious is more helpful then being a technical genius in that link. It makes sense in this case. That was a very interesting article. Thanks for the link

If you want an easy alternative to asterisk and trixbox take a look at http://www.3cx.com.

The free version is more then adquate for a small business or home system and it runs under XP profession or windows 2003. You can set it up with free voip soft phones to test and then find a voip provider in your country. This is 100% SIP based so if you want to connect to local phone lines you go thru a gateway and for long distance you can save a ton finding a good voip supplier.

we do not intent to find a voip provider we wish to become our selfs a voip provider with out the need of a 2rd middle service betwen.

We use to use varphonex because of their unlimited plans but many callls we use to make had a lot of delays or had a really bad quallity so we are now in this study to see if would be a good option for us to make our own ... we have a lot of clients and our company works in brazil, uae and usa...

The voip will be mainlly for brazil. We have a 40 mb link and 2 quad core around with no use that we could use... We have some experience with asterisk as we have used it for callcenters.

thanks for the reply.

nuke13 thanks for the link it was very helpfull.

Our greater concern would be to be able to present for our customer a DID from any city in brazil as well as a 0800 that for us is iqual to a Toll Free.

In all likely hood, you would find the cost of doing so, quite expensive. First off, the interface with the 'regular' phone systems is quite expensive. You must have live connection to it via some sort of 'hard' connection (All of the other providers do this already for you.) In Europe, and parts of Asia, you would use a ISDN BRI/PRI, or a E1. In the US, you would use a T1 (or other digital line.) You could use a Analog line, but that would only allow one call per line, whereas a E1 will allow, I believe 32 simultaneous calls, and a T1 will allow 24. (I don't know E1 very well, as I work in the US, and only know T1.) I don't know what Brazil, or UAE uses for digital connections, but I would guess E1.
You would also require a interface card for each server, so that it can interface with the E1/T1. (There are several companies that make such cards that will work with Asterisk. Digium, make a few, and they also wrote asterisk, so those cards are guaranteed to work. Sangoma also makes a few cards. I know there are others out there, but they are less supported for asterisk, and I don't know much about them, so you would want to check them out before investing in them completely). I believe Intel has some Dialogic cards that work great, but to get support for them in Asterisk, you have to buy the professional version, as the free version does not come with the drivers.

Also, you would need a presence in each country in order to patch into their 'regular system. (In the US, this is called PSTN, or Public Switch Telephone Network). So therefore, for each location, you would need 1 server, one interface card, and one physical connection to the PSTN/regular phone system. Also, you would need a fast, low latency connection between each of the 3 servers. This is only to get you a presence in one city per country, and for each extra city you want a presence in, you would need an extra server, card, and hard line.

connecting to the PSTN/regular Phonesystem is a heavy, and expensive thing to do, and I would suggest you do some very heavy market research before jumping into it. That being said, if you can pull it off, you may very well have a GREAT product you can sell at a lower cost then the regular groups sell, which would allow you to connect overseas calls for a much lower price than the competitors in the 'real Telcos'

Hope this was a help!

Nothing to add to the thread apart for some thanks to WebGuyz for mentioning this setup.

After months of fighting asterisk, I had this all up and going in about an hour!

Cheers

@refuge
or any capable user...
I want to start a small business to make international calls via cell. The cell user1 from country A will access local voip server (with Analog or line that can make multiple calls at once) via mobile web to dial international number, local voip server will callback cell user1 (like google voice), when user1 picks up, the voip server connects to voip server in country B, then the voip server dials cell user 2 and then connects them to talk via cell. How can i achieve this project. your help will be much appreciated and rewarded when project lunches. email me at kyngsigma@gmail.com
