In the attached packet capture, and decoding the packet as RTCP, an RTCP XR
VoIP Metrics report block contains the byte 0x2c at offset 0x7c and 0x7d for
the fields 'MOS-LQ' and 'MOS-CQ'. 

Expected result: According to RFC 3611 section 4.7.5, 0x2c should indicate a
MOS value of 4.4.

Observed result: Wireshark displays 4.0 for both 'MOS - Listening Quality' and
'MOS - Conversational Quality' in the Packet Details window.

Observed in both Wireshark 0.99.5 and 1.0.0.
