PhotonVoice eats more than 30% of my frame rate, how can I improve performance?

Hello,

I am having big performance issue with PhotonVoice as it eats away more than 30% of my frame rate, consistently. See Unity Profiler Screenshot: http://i.imgur.com/kcQKpdL.png

My setup is pretty minimal: only 2 clients in a room sending voice data to each others.

What would you recommend I do to improve performance? Any settings/code I could tweak?

Thank you!
