Bandwidth use for Voice over IP communications

Depending on the VoIP codec deployed in a conversation the bandwidth varies. Nowadays (2011) modern systems normally use either G.711 (IDSN quality) or the newer G.722 (HD Telephony) codec. Both codecs use 64 Kibitz for incoming and outgoing conversations. Anyone how is interested in learning more about bandwidth consumption should take a look at the free bandwidth calculator here.
