Zebedee with asterisk?

Has anyone tried setting up Asterisk with Zebedee (winton.org.uk/zebedee/) tunneling software?

Just curious as some companies would want some type of secure communication between say, offices. For smaller companies that did not have WAN service between offices, I was thinking that it would be useful.

I’ve never used Zebedee, but have heard of several people using to tunnel through to a FirebirdSQL server.

Thanks,

Lee
