What bandwidth is required?

We recommend an overall bandwidth of 100kb in transmission and 100kb in reception per user ?.

These 100kb create an ideal scenario for an HD voice call via Chrome ? with tunnelling: 48kb/s bitrate + 20kb/s error correction + the TURN/TLS headers; the upper limit being 100kb/s.

For a classic SIP call via IP phone ☎️:

  • G711 codec: 64kb/s

  • Opus codec: 12.4kb/s => 48kb/s +/- error correction
