Setting DTMF

This setting is available under Settings and Preferences.

Select a method Bria uses when using dual-tone multi frequency (DTMF) or interactive voice response.

You may need to change this method if you cannot interact with interactive voice response systems — auto attendants, voice-activated menus. Contact your VoIP service provider or your system administrator for the correct setting.

  • Send via RFC 2833
  • Send via INFO
  • Send in-band

In-band means that Bria encodes DTMF signals in the audio stream as regular sound. Typically, DTMF is not send in-band.

You may want to use in-band if all three conditions apply:

  • You own your own gateway.
  • One or more gateways do not support RFC 2833 or do not handle it well.
  • Your gateway is using codes that reproduce DTMF codes well.

In this case, sending in-band ensures your DTMF tones get through because they bypass the gateway and they are reproduced accurately on the receiving end.
