Jitter buffer is now based on packets, not on samples. The frames are
dejittered in received form. After reading from jitter buffer, they are
decoded in correct order. If a frame is missing, it is concealed by
repeating audio.
A voice message can be sent with a wave file. Pagers that support voice
messages will listen to the wave file on the radio channel.
Use the following command to send a voice message:
$ echo "1709829,v,<wave file>" > /tmp/golay_msg_send
