[Asterisk-Dev] Voicemail Envelope (cid, date/time playback)

[John Todd]

This is a good start!  However, your inspiration was perhaps too 
well-founded.  Tilghman has created some really well thought-out 
patches to do just what you're doing, with customizable date/time 
zone speech syntax and per-user methods for date/time readout.  He's 
said that he'll have some additional time to finish the patches and 
apply to Voicemail and Voicemail2 shortly, but they're already almost 
done from what I've seen.

His patches play the received times at the beginning of the message, 
instead of as a DTMF sequence trigger inside the message.  I don't 
find that to be too much of a problem, especially with the 
customizable date/timestamps for each user or group (yes, there are 
defaults.)

There is additional delay in that I have to get a handful of 
recordings done to support the extensions, but that should be no big 
deal.
