It's the combination of wireless packets dropping and the audio having to be degraded to 8bit/8kHz to pass between carriers that really brings on the terrible.

It's the combination of wireless packets dropping and the audio having to be degraded to 8bit/8kHz to pass between carriers that really brings on the terrible.
