GSM RR DTM Assignment Command msg is decoded as Packet Assignment Command
DTM Assignment Command type=0x4c
Packet Assignment Command =0x4b
in packet-gsm_a_rr.c
{ 0x4b, "Main DCCH Assignment Command" },
{ 0x4c, "Packet Assignment Command" },
{ 0x4d, "DTM Assignment Command" },
it is wrong
0x4d= DTM INFORMATION
see 3GPP TS 44.018 section 10.4 message type
and in current version , only msg type is decoded and display,
can you decode fields in DTM Assignment Command just like Assignment Command?
Thanks
