<DIV><FONT face=Arial size=2>Note: The exclamation mark wildcard, which is
available only in Asterisk 1.2 and later, behaves specially — it will match as
soon as can without waiting for the dialing to complete, but it will not match
until it is unambiguous, and the number being dialed cannot match any other
extension in the context. It was designed for use as follows, so that as soon as
the digits dialed don't match '001800...' the outgoing telephone line will be
picked up and overlap dialing will be used (with full audio feedback from
'earlyb3' etc.) </FONT></DIV>

<DIV><FONT face=Arial size=2>So then can I have _!800NXXXXXX to match someone
