My D715 is not playing any music when I put a call on hold.
I have also tried to upload a custom WAV file, although I thought there should be one pre-installed. I did all the steps, creating a audio file with the specifications, create a XML, update via settings URL etc. The log indicated, that the "moh" wave file was updated successfully.
Still, when I've got a phone call and press the "hold" button, the other party only hears silence.
In "Advanced Settings" > "Audio" the setting "Play music during hold" is set to "on".
Am I missing anything? Why does it not work?
BTW: I have downgraded to firmware "snom715-SIP 184.108.40.206" because I was having issues with the latest version.
