Hi,
The capture you posted shows a SIP signaling message between a mobile
and a SIP entity with the mobile SIP client getting a 401 unathorized
message. The message was probably captured on a 3GPP mobile network,

S1-U or S5
Hi,
It is because Dissect T-PDU option must be enabled in the GTP protocol

You can do following:
Edit menu -> preferences -> protocols -> GTP -> disable dissect T-PDU
Hope this resolves your problem.
