[Mac-telephony-list] LinuxPPC & * or OpenPBX?

[Thoth via List]

From my standpoint it seems a much more logical route to dedicate a linux 
server to the task of asterisk/pbx.  Minus the graphical overhead most 
hardware should be able to push at least an answering machine functionality.  
As for OS X, seeing as how this a mac list after all, I think a profileration 
of monitoring and configuration utilities like Ivan's is the perfect use.  
Kudos to Ivan and the Sun telco people which are doing exactly that.  

Does anyone see an advantage to running asterisk on OS X, aside from maybe a 
all-in-one secretary's desktop that runs word processing, 
spreadsheeting/databasing, and answers the phone?  I don't think there would 
be any more stability to be gained from OS X.  And the graphical overhead is 
a waste if the box is only a server.  Add in samba sharing, ldap, 
openexchange, email, and web services, and a linux server can provide a ton 
of corporate level phunctionality all with no licensing fees.
