Echo cancel when streaming voice full-duplex using gstreamer!

[haonc]

Hello everyone,
I'm facing with a big problem when streaming voice full-duplex between two devices using gstreamer. It's too much noise and echo. Anyone has any idea for cancel echo with gstreamer? Does gstreamer support element to cancel echo? I'm using gstreamer version 0.10.32.
Thanks for your reading !

Echo-cancelling is a feature usually provided by your audio deamon. As
an example, on Linux this is part of pulseaudio. You can enabled echo-
cancelling feature on pipeline with stream-properties.

gst-launch-1.0 pulsesrc stream-properties=props,filter.want=echo-cancel ! pulsesink stream-properties=props,want=echo-cancel

I doubt this was ever supported 6 years ago (0.10.32 is very old). The
0.10 ABI has been abandoned now, and is no longer updated. You also
need a recent enough version of the pulseaudio daemon.
