Summary

Adds typed SIP sideband keypress commands and delivery confirmations while preserving legacy notification types.

Changes

  • Send SIP keypresses with transport.dtmf.send and optional event correlation.
  • Receive transport.dtmf.sent confirmations while retaining existing transport.dtmf.send notification types.

The transport.dtmf.send command is available for SIP sideband connections. Successful sends produce transport.dtmf.sent acknowledgements. Legacy SDK notification types and historical event decoding remain available, while the server acknowledgement now uses transport.dtmf.sent.
