Asterisk doesn't support silent audio generation, but there is a simpler use case of simply dropping audio when a channel is muted. With the LPC10 codec, even when there is no audio in one direction, traffic does not appear to decrease, which would be ideal for extremely low bandwidth use cases. Modifications to channel.c and/or chan_iax2 should be made to allow for no audio (e.g. empty audio frames, or null frames) to be sent when the transmitting channel is muted.
