this does not seem to work,
when i change the prompt on settings > on hold music > music file 0
onhold_low.wav witch is the default.
Nothing will change even if i use the same name onhold_low.wav
also somewhere hidden in de 3cx program folder you will find onhold_low.wav but replacing this file will also do nothing.
i did not restart the 3cx services (running on windows server 2019)
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
