Reply To: IP Telephony vs Voice Over IP


Hi Frank,

Thanks for replying to my post. Today I just called to a company and I ask about the main differences of this technologies, and the person who attended me said to me that the main difference is that ip telephony uses a microphone connected to your computer to talk with another person. But this is half-duplex.

The voice over ip technology uses the regular telephone with an adapter that digitize the voice, and is full-duplex.

If this is true please let me know. But I don’t think this answer is true, comparing to the bunch of information that I got, incluiding yours.

And another thing, this homework was assigned to me by a very, very tricky professor.
Thanks in advanced,
