If you use bobrtc and want to play audio when calling up scammers to annoy on bobrtc there are a few things you need to do.
First you need discord set up which should be pretty straight forward.
Then use this link to install audiopick on google chrome which will enable you to switch to the right audio input once everything else is set up.

Get vb cable installed and voicemeeter banana installed then reboot windows.
After that get resanance which is a soundboard software that will enable you to play sounds.
When on voicemeeter banana select vb audio as one of the inputs and select any other microphone/headset if needed.
After that choose the speakers you are using in voicemeeter banana and there will only be a few more steps.
In resanance choose the input that says vb audio and the one that says vaio and not the aux one.
Next you just need to find some decent audio you would like to spam to annoy the hell out of the scammers when calling them
I would recommend audio of mooing cows which should both confuse and annoy them.
Also make sure in windows sound settings that the default microphone is set as the voicemeeter vaio option.
I also forgot to mention you need vb cable open when doing this and make sure you choose the one that has vaio in it and not aux in it which was a mistake I did when first installing it.
After all that you should be good to go but make sure you have selected the right audio input when calling in case you can't hear anything.
I had to experiment a lot to make everything work the way I wanted and in the end it was worth it.
And now there finally is a good updated tutorial written by me that does not use firertc that tells you how to set up a soundboard when calling scammers.
