Hello,

I have a Dahua VTO2202F-P-S2 which unfortunately doesn't support the ONVIF Profile T (at least it didn't work in my tests).

I wonder if it's reasonable to suggest supporting additional methods for playing the audio in the camera/doorbell. For example, this doorbell exposes a small API which allows me to play audio on it:

https://s3.amazonaws.com/amcrest-files/AMCREST_CGI_SDK_API.pdf
(search for Post Audio)

I can reproduce it with something like:

curl --digest -verbose --request POST --url 'http://admin:[email protected]/cgi-bin/audio.cgi?action=postAudio&httptype=singlepart&channel=1' --header 'Content-Type: Audio/G.711A' --data-binary '@DoorBell.wav'

So I wonder if it should be possible to pipe the audio from browser to this API in order to achieve 2-way audio.
