While pyvoice works quite well, it doesn't allow voice ignore i.e. a user in the chatroom cannot be ignored on voice. The ignore option works only for the text and has no effect on voice.In the pyvoice dialog, there is an option to ignore, however it stays disabled.
Another thing that I noticed is that once the talk button is pressed, we cannot hear what the other party is saying.
These are the 2 main features that I would love to be given a higher priority on the wishlist.
