Here are two CME little bugs that to my knowledge don't even have a number yet, still I have observed since quite a time:
1. Under ephone-hunt, configuring "no list" and then "list ..." again, makes the secondary pilot number to disappear from config.
2. Under "voice register global", the dialplan-pattern command, when configured with the extension keywords, does not let you configure the unrelated "no-reg" keyword.
Minor but still very fixable annoyances :)
