[KLUG Members] Open-source voicemail?

[Adam Williams]

>I'm looking to replace buggy proprietary software which provides
>essentially a very complex voicemail system.  The replacement would
>have to allow me to flowchart which number-key presses lead the
>caller where, and allow me to play sound samples and optionally
>record the user's responses.
>Presumably this would use a voicemodem of some kind or perhaps a bit
>of custom sound hardware.  And if it provides a friendly frontend
>for dealing with incoming voice data, great, otherwise it should
>drop that data into an open format that other programs can read.
>What I've found so far are these.  Does anyone know whether any of
>these would suit my needs?
