Summary:                    [patch] Empty messages should not result in a
voicemail
Description: 
When a message consists of all silence a message file is still stored on
the server and a notice is sent to the user.  This is a very annoying
behavior to check voicemail and see that there is no actual message.

Included is a patch that changes the default value for vmminmessage to 1,
stores the cumulative silence value and compares the length of the message
vs. silence detected.  If the difference is greater than 0, it's a message,
otherwise, discard it.

Even with this patch, some silent messages can potentially make it
through, due to the 1 second granularity of measuring message length.

please disregard silent-vm-1.6.2-fix.txt and apply silent-vm-1.6.2-fix2.txt
instead.  the former will pass messages that end in silence and maxsilence
will be ignored
