Internet Telephone

With all these choices you'd think so but it's an anomaly that the powers that be are rigorously covering up.

ATDT was the first protocol
ATDT gave the computer user the protocol for BBSing (ringing up another computer directly to the other computer's modem, a telephone as such)
the bulletin board was set up to firstly convey computer data across the telephone lines directly between two computers at different locations.

The sender and the receiver computer both had to be set up the same for the BBS (bulletin board to work commonly using such programs as "Qmodem, bluewave for chat and various others.

ATDT is the normal language that is used for your standard phone.

Then came TCP/IP (transmission control protocol/Internet protocol) and our settings had to be changed to suit this newer protocol from Software (XON/XOFF), to the new hardware (RTS/CTS) which made your modem work on the internet via your internet service provider.

So now with these two protocols, "hardware" settings are for TCPIP and the old "software" setting are for things such as modem to modem direct calling (via telephone lines) and PC fax to inline faxing or direct PC to phone calling via software such as the older version of Supervoc which had the ability to call directly from a PC to a house phone using the PC's mic and speakers (now desidedly made obsolute in the newer versions)

And now with the new up and coming VOIP you'd think so, but alas not if one of the comunictives is still using the old copper wire or ADSL (yet unexplained, in short broadband over copper cable at a different frequency to your ATDT phone)
for those on CABLE it may be a good alternative albeit notwithstanding the above exception (the other user). and of course not to a land line thats not working (did I really need to say that?)

So your choice (or is it just a choice of the people that are trying their best to make a (billion$) buck out of us bewildered n00b's.

VOIP = a way of recharging people that already pay for TCP/IP connection to pay for using a cordless telephone connected to your computer to talk through that TCP/IP connection to an ordinary phone.

Remember this about our already paid for internet services provder's:
We can send text messages to cell phones via ICQ (FREE)
We can talk to people around the world via chat programs to chat programs (FREE)
We are made to pay extra for talking to those same people on their phone lines at rates such as supplied by "skyPE" and others (PC to land line)
We still pay for landline to land line phone calls at the suppliers rates

Telephone company's are dubiously tring to get manufactures to build VOIP units to plug into our computer for use with MSN-LiVe to extort money for VOIP when the same is redirected to and fro via TCP/IP between the countries as it is more efficent, and already being paid for by the customer (THAT's YOU)

So tell them to give all of us TCP/IP and get off the grass with the dedundent foul play.

An even better solution would be to open up saterlite transmission for global use and get rid of all the other redundent transmissions.
Even Tesela proved that it is possible to transmit globally even without saterlite usages and relying completely on a ground based infrastructure of wireless base communication.

To answer your question yes if they use wireless and no for copper cable users be it modem or adsl.

Let me repeat "Is there technology available for communicating [or talking] from one's PC to a landphone located at another country?" This information is very useful,to maintain communication, when the normal telephone network totally fails.

Yes, there is many carriers with different technologies avaliable, if you can explain more what are you looking for, or what exactly you mean with technology that will be useful

Thank you very much for the information. Sorry for this delay in replying to you.
