A Word About Default Parameters

By default, Intercom is set to communicate over low-bandwidth links. It uses a sampling rate of 8000 samples per second compressed using the GSM CODEC. This consumes 13.2 Kbit/sec or 1.61 Kbytes/sec in either direction. If you have a high-speed connection, you can achieve much higher audio quality by changing the compression format used and the audio sampling rate. This is discussed further in the next chapter.
