>Support for RTP header extensions is probably going to be needed in the future for other applications (e.g., transmitting some WebRTC streams), but I want to >understand where/why people might already be using them for other purposes.

An application for the RTP header extensions is in VoIP Air Traffic Management for radio communication. The EUROCAE standards ED137 part 1: Radio states:
“The Real time Transport Protocol Header Extension will be employed to transport the following signalling information in real time:
a) PTT (Push To Talk)
b) Aircraft Call (A/C call), also nominated Squelch (SQL);
c) Quality index (used for the Best Signal Signalling feature)
d) Time stamping information (used for CLIMAX application)
e) Reserved field for proprietary applications f) Keep alive message
“

ED137 part 4: Recording, describes how to record ATM voice communications and metadata using RTSP.
