I need VOICECHAT in my open tibia server. (engine TFS 0.3.6, client OTClient v8) C++ / LUA

I am looking for a skilled programmer to add a voice chat feature to my client and server, which are both built in C++. I have all the necessary documentation to provide when it is required. I am open to suggestions in regards to which voice chat software to use, but am expecting professional input before making a final decision. This project needs to be completed within 3-7 days, and is crucial for the functioning of my product. I am ready to hire the person who is able to meet these requirements and exceed expectations.
