- In this time, I’d like to explain about my company and my job.
- My company develops and sells the solutions regarding the internet telephony.
- When we call someone, we usually pick up the phone and dial the number.
- And then after waiting a minutes, we can be connected to the other side and start talking.
- On the surface, my phone seems to be connected to the other phone directly.
- But, the telephone line of my phone is connected to some equipment at a telephone company.
- That equipment analyzes the number that we dialed and searches the phone that we want to connect and then finally connect each other.
- We call this equipment “telephone exchanger”.
- In the past, telephone operators of telephone companies connected calls manually.
- But these days. All process in regard of calling became automated.
- All process is conducted by automated machine, “telephone exchanger”.
- until several years ago, we called with analog phones and analog telephone exchangers.
- But these days, many people and companies are using internet telephony.
- Internet telephony means that we can give and take our voice on the IP network not PSTN network.
- When we use internet telephony, we can reduce call charge dramatically.
- It’ because we don’t need to use physical telephone wire and in the IP network, regardless of the distance, it applies the single low call cost.
- So, especially, it provides the low international call.
- Now, thanks to Internet telephony, we can study English between Philippine and Korea at the low cost.
- My company develops internet telephone exchangers called "Softswitch" and sells them to the telephone companies(Internet Telephony Service providers).
