Hi there,
We implement Zoom SIP connector integration with our hardware encoder and I have a question about DTMF Digits RFCs that Zoom SIP connector supporting. There are two RFCs, https://tools.ietf.org/html/rfc2833 and https://tools.ietf.org/html/rfc4733. So it seems that Zoom SIP connector supports rfc2833, but I’d like to know does it support rfc4733?
Thanks,
Alex
