Why does wireshark decode AMB-WR data as "Octet-Aligned Mode" instead of "Bandwidth-Efficient Mode"?

Hi Community, Greetings from me! I have an original pcap file whose RTP payload type is AMR-WB, and it uses "Octet-Aligned Mode" to encode data. Then I just changed the octet-align from 1 to 0 in SIP/SDP message (The 1st packet, fmtp:123 octet-align=0), and hope the wireshark can assume the data as "Bandwidth-Efficient Mode", but the wireshark still decodes the AMR-WB encoding as "Octet-Aligned Mode". Could anyone advise me on this issue? Thanks very much for your time in advance! (The pcap file is attached) Best Regards Nan Xiao
