I have wireshark capture for VoIP with AMR-WB. My capture does not have SIP transactions. So I have set the RTP preference field to decode the RTP packets with appropriate payload type as AMR-WB, octat aligned. I am able to see decoded packets. However, the protocol field shows it as only AMR. The field type bits are properly decoded though to AMR-WB 12.2 kbits. Again, for SID frametype (value 9), I get illegal Frametype - For future use (9). I am using version 1.8.6

That's the way it's designed, the protocol is AMR.
Sounds like a bug could you raise a bug report and include a small sample trace and indicate which packet to look at and how preferences should be set.
