r350938 | seanbright | 2012-01-16 16:27:57 +0200 (Mon, 16 Jan 2012) | 5 lines
Sort the output of 'database show' by key.
This more closely mimics the behavior of 'database show' before the conversion
to sqlite3.
........
r350976 | file | 2012-01-16 19:06:05 +0200 (Mon, 16 Jan 2012) | 5 lines
Add missing code to set direct RTP setup information during dialing.

r350978 | seanbright | 2012-01-16 19:11:39 +0200 (Mon, 16 Jan 2012) | 5 lines

You can pass wildcards (%) to the database CLI commands, so this will sort the
returned list of matches.
