Ip telephony for blondes

One of my favorite achievements of modern science and technology is ip telephony. AND
If earlier I had a very vague idea about this, then when my mother moved to America (2 years ago), I had to think. Because the amount of money spent on a mobile phone was an insane amount, but the feeling that I hadn't said everything yet remained permanent. Love, you know, chat.
Everyone knows that IP telephony is cheap and of high quality. True, a bit complicated. I
far from immediately figured out with such an unusual way to make a call. But if you approach this case thoroughly, no problems will arise. That is why I decided to devote my article to this issue. I hope that it will be useful not only for blondes =).
As a material for proceedings, of course, I will use the site of our company.
e1tele.com . We offer users one of the following technologies: callback or callin.
Despite the obviousness of the names, there are nuances that will be discussed below. Illustrations on the text to help girls =).

1. Technology callback (callback) allows you to connect two phone numbers so
This means that the call for each of them is incoming and, therefore, is not charged by the service provider. That is, when ordering a call, E1tele.com first dials to one subscriber, then to the second, and then connects them to each other.
You can make a call to e1tele.com/Home/Rates.aspx in three ways:
• sending sms from your mobile phone e1tele.com/HowItWorks
HowItWorks.aspx,
• installing a special program e1tele.com/HowItWorks/ServiceIndex.aspx ?
op = 0315,
• by dialing the access number e1tele.com/HowItWorks/HowItWorks.aspx .
callback

2. A call to callin technology (direct call) is a bit easier to make. You can, for example,
dial the access number, and then, following the instructions of the system, dial the number of the called subscriber. At the end of the call, the cost of the call will be written from the account of your phone
callin
')
There is another option - a call using a SIP FLASH phone. This is a program that
reproduces the look of a familiar telephone set. In this case, no access numbers are needed - just register on the site, click on the application and dial the number of the interlocutor as if from a regular phone.
Thus, when calling a callin, only one outgoing call is made, which
is charged accordingly. That is why callin technology calls are usually
cheaper callback (one outgoing versus two inbound).
