[Asterisk-Users] Two companies - One Asterisk???

[Noah Silverman]

We have two small business that run out of our office.  One business has 
3 phone lines, and the other has only one.

In a perfect world, Asterisk would indicate WHICH line (or group) the 
outsider caller called, so that we would know which way to answer the 
phone.  The incoming calls would go through a voice mail menu first - 
different for each company.  (Press one for sales, two for accounting, 
etc.)  Whatever they pressed, the correct extension would ring, show the 
caller id correctly, AND indicate which outside line (or group) the call 
came in on.

I'm running the Polycom IP500 phones.  I think, from Noah Miller's 
suggestion, that there might be a way to use the "line" buttons on the 
phone.  Tie a group of lines to button one, and a group of lines to 
button two.  I just don't know HOW to do this.  (For the record, I'm 
using the Zap interface for incoming POTS lines.)

Thanks!!
