We're using react-sip for a project at our organization, and we needed DTMF support, so I took the liberty of adding it to react-sip.
Note that this is RFC-4733 DTMF, so DTMF in the RTP payload, rather than JsSip's SIP INFO implementation. This could be added, but doesn't fit our specific use case as we connect to PSTN providers who don't support SIP INFO (and therefore I won't be allocated time to do it 😞).
