Why is ASTRA listening to me without my PTT key being held down?

[Tentaryn]

Hi All,

An annoying thing I have is that sometimes ASTRA will, for whatever reason, say 'voice control on' without me holding down my configured PTT key. I've also noticed if I say 'voice control off' she responds, again without me holding down my PTT key!

How is this possible?
