Your concern would be addressed by the use of SDES-SRTP rather than
DTLS-SRTP.

SDES-SRTP would provide, in the context of WebRTC, the transport of SDES
key over HTTP(S) and so would let all existing methods for HTTP/HTTPS
inspection to works fine.

Technology for inspection of HTTP/HTTPS traffic already exists, are
widely deployed and so if we transport keying material over HTTP (with
SDES-SRTP), all Enterprises will already have their existing
infrastructure in-place.
