ABSTRACT:
This invention relates to a method and apparatus for transmitting frequency shift key (FSK) data in packetized format. More particularly, the invention is directed to a method for using a new Real-Time Transport Protocol (RTP) payload type to transport FSK data used for voiceband data transmission outside of the voice RTP stream. This technique allows for data compression and reduces the possibility of packet loss for FSK data carried in-band.
