[asterisk-users] Asterisk Bible?

[Tim Densmore]

Hi Folks,

Is there a generally accepted Asterisk bible for current versions?  I 
poked around the forums and there didn't seem to be a real consensus, 
and there are lots of options out there.  I need something that focuses 
on Asterisk dialplans and config files, not a linux primer.  I'm looking 
for dead-tree rather than online documentation.

Thanks,

Tim
