What I want to do
The purpose is to be able to input an audio from a microphone on a PC and send and output audio from the audio output terminal of the IP camera.
Where it's jammed
I want to receive a response like the image below using curl for an ONVIF compatible camera, but the expected response is not returned. I'm wondering if the DESCRIBE part is written incorrectly, but I haven't found how to fix it.
ONVIF Core Specification Page 211
What I tried
$ curl -v -X DESCRIBE "rtsp://admin:password@192.168.1.212:554/Streaming/Channels/101 RTSP/1.0" -H "Content- Type: application/sdp" -H "User-Agent: ONVIF Rtsp client" -H "Require: www.onvif.org/ver20/backchannel"

I would appreciate your guidance. Thank you in advance.
