OPUS "Use DTX" setting is ignored in 200 OK messages

[leamingrad]

I have disabled the "Use DTX" setting for OPUS in my jitsi client. However, when the client receives an invite, it replies with the following SDP in its 200 OK:

v=0
o=3162030020-jitsi.org 0 0 IN IP4 192.168.80.10
s=-
c=IN IP4 192.168.80.10
t=0 0
m=audio 5089 RTP/AVP 97
a=rtpmap:97 opus/48000/2
a=fmtp:97 usedtx=1
a=ptime:97 20

In particular, the usedtx=1 header should not be there as that is indicating the use of DTX. This was seen when using version 2.9.5519

On further investigation, this is on INVITEs as well as 200 OKs

You need to restart Jitsi for the Use DTX setting to become effective.
