Hi,
---> I opened the tnt-call-deciphered.pcap file that you uploaded with wireshark.
---> Then I opened the osmo-gmr code. I got a wireshark output myself using tnt-call-268-93600.cfile , tnt-call-267-93600.cfile and the password.
---> In the resulting wireshark output, the section with (CC) Setup appears as Malformed Packet.
a) What is the cause of the Malformed Packet problem?
b) How can I fix this problem?
