Hello,

We have found that below IE of GSM "Assignment Command" is not showing correct description for "Channel Mode": instead it shows Unknown.

It's value is 0xc3 and as per 3gpp TS 44.018, it is 1 1 0 0 0 0 1 1 speech full rate or half rate version 3 in VAMOS mode (Note 3)

PDU hex is: 06 2e c1 94 9d 05 05 10 00 00 03 ff ff ff e0 00 00 00 00 00 00 00 00 00 63 c3 03 06 20 95 0c 24 4d 93

Channel Mode - Mode of the First Channel(Channel Set 1) Element ID: 0x63 Channel Mode: Unknown (195)

That is something to be reported at bugs.wireshark.org, preferably with a sample capture file. Then it can be looked at, and if need be, fixed or added by someone who can write the code and has time to do so.
