[Asterisk-Users] Receptionist Phones

[Daniel Hazelbaker]

For those of us that only need a small handful of these receptionist  
phones (for me it is 2), it should not be nearly as much of a  
problem, correct?  For example I only need 2 phones with 60 (well, I  
can get 54 atm, but would like to expand even more).  Assuming  
everybody picked up their phone at the same time that would only be  
180 (60 * 2, plus I am assuming some message to the phone that was  
picked up) messages.  I can't imagine putting a sidecar on every  
single phone.  If average joe really wants to know if somebody is on  
the phone they can log into a web page that will tell them the status  
of a phone.

Daniel - Good to hear that people from the manufacturing companies  
traffic these lists!
