See attached sample capture with sample packets from two different H.248
contexts (383 and 54). When using the display filter megaco.context==383 in
this capture file, the three packets corresponding to context 383 are
displayed. When using display filter megaco.context==54 in the file, no packets
are displayed, even though there are three packets in the file from context 54.
However, putting 54 in double quotes " " causes the filter to work. These
double quotes are *not* required for the filter to work with context 383,
leading me to believe that below a certain threshold (maybe less than three
digits?) wireshark is possibly interpreting the value as a number instead of a
string, so it doesn't work.
This should at least be consistent one way or another, and preferably should
work without quotes entirely, for this display filter.
