Hi Stefan, As I understand it, the licenses you point to are either for = developing/using your own implementation of PESQ, or for using the = official implementation. If you use a third party implementation it is = their responsibility to obtain the proper licenses, not yours. Perhaps = Graham, can help clarify Opticom's position on this.
