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
