When decoding ANSI MAP, Wireshark detect BER encoding error on a missing field:
 BER Error: Missing field in SET class:2 (CONTEXT) tag:22 expected

This is apparently because systemMyTypeCode is defined as Mandatory in several
of the ANSI MAP operations.  In fact, according to IS-826 Part 5 August 2000,
this element is only Mandatory in the TransferToNumberRequest INVOKE operation.
 In all other operations where it is allowed (ServiceRequest,
AnalyzedInformation, Facility SelectedAnd Available, TBusy, TNoAnswer, OAnswer,
ODisconnect, TAnswer,  TDisconnect) this element should be OPTIONAL.

This is the first Wireshark bug I have ever reported.  If you need more
information, or a test capture file, please let me know.
