Default Phone mute - how does that work

I thought I was paranoid, but as fare as I'm aware the monitoring of
telephone calls on hold is not a practice done by the dept of work and
pension.

experience into a viable and meaningful comprehension...

Waiting to get through to Plusnet's support, they play music whilst
waiting. If their is any noise in the room, the music mutes, however
they also break into the music to make a regular voice announcement -
the voice announcements are NOT affected/ NOT muted by noise in the
room. Best guess is that Plusnet's system listens for noise on the line
and mutes just the music.



I don't really know why they are doing this but I am prepared to
engage in speculation.

It occurs to me that their music on hold might be configured to mute
when inbound audio is heard in case a valid DTMF tone is sent by you
to their IVR, so the music does not swamp it.

In theory this is not necessary as the TX and RX is separated out,
including in the "hybrid" circuit of your telephone, but in practice
there is always some leakage, some of it intentional (sidetone)


On a related matter I have pondered whether, when you call an office
dealing with "benefits" or insurance claims, if they record the call
while you are waiting to be put through to the department, in the
"hope" that you will conspire with someone else in the room about the
fraud you are engaged with.
