Wireshark TCAP BER error

Hi Community,

I am trying to decode a GSM-MAP message and always see an error in the TCAP layer as 'BER Error: This error lies beyond the end of the known sequence definition.'

This error is only in the first MAP-PUSSR and MAP-USSR message, rest all messages are fine. I am using Wireshark version 1.6.1 to capture data. Kindly note MAP is running on SCTP.

Thanks in advance!
