Play licensed AMR codec RTP packets in Wireshark

Hello Guys,

AMR codec RTP packets cannot be played in wireshark, since it is a licensed codec na.
Do you have any idea, what other way to play it?

I have tried these two links (below), but unsuccessful.
I will be happy to know if there is a successful way of playing the AMR packets.
