[asterisk-users] using asterisk on a shared line

[Pascal Bruno]

Just a little clarification for people refering to Asterisk as a PBX  
and not an Answering Machine:

In fact, Asterisk is neither a PBX nor an Answering Machine. Asterisk  
is a Telephony Toolkit. You can choose to use it as a PBX or an  
Answering Machine or both or even in some case as a something  
different than a PBX or Answering Machine. You should know that  
already, so this is just a reminder :-)
