Abstract
A telecommunication system routes wireless-specific digital frames from a first wireless communication device across a data-oriented network, without vocoding, for information delivery to a second communication device while implementing multi-party conferencing and tone/announcement generating functionality. Tone and announcement generation services are provided while the call path retains the wireless-specific digital frame format between the first wireless communication device and the terminating gateway. When tones are generated by the first wireless communication device, signaling messages are sent directly to the terminating gateway vocoder to initiate the generation of full rate DTMF tones at the terminating network. When tones and announcements are sent to the first wireless communication device, a resource server, working together with a feature server, generates a wireless-encoded version of the tone or announcement. This wireless-encoded version is then sent to the first wireless communication device, where an audible version of the tone or announcement is produced. When multi-party conferencing is initiated, the first call is established via wireless-specific digital fra…
