Voice chat crash iOS with Android

Hello, I have an issue for a while now I’ve been trying to crash but with not a lot of success and that is iOS is crashing whenever Android is using voice chat. Albeit, we are using Vivox for our implementation, but I am wondering if someone else got this issue before and was able to fix it.
