Summary

  • Wires the SDK's onDtmfSent callback (added in javascript-brtc-sdk#16, published in bandwidth-rtc@0.8.0) to flash the corresponding digit on the dial pad when a tone is actually played on the outbound stream.
  • The indicator reflects the SDK's confirmation event, not the click itself, so it also lights up when a digit is sent via the sequence input rather than the grid.
  • Bumps bandwidth-rtc from ^0.6.0 to ^0.8.0.

Jira: https://bandwidth-jira.atlassian.net/browse/VAPI-3804

Test plan

  • tsc --noEmit passes (pre-existing unrelated errors in server/types.ts only)
  • Manual: place a call, send DTMF via grid clicks and via the sequence input, confirm the pressed/sent digit flashes
