  • Method and apparatus for internet protocol voice based telephony communication
    Patent number: 7046771
    Abstract: A method of providing a sound file to a voice gateway for coupling the voice gateway to a receiver via a voice based telephony connection. The method includes the steps of establishing a connection to the voice gateway, dividing the sound file into smaller files with a reduced size, altering the sound file header to reflect the smaller files size. The altered file header is attached at the beginning of the smaller files. The smaller files are converted into a format usable by the voice gateway.
