[kwlug-disc] asterisk busy lamp

[Insurance Squared Inc.]

We're running asterisk for our office phone system with the spa941 
phones.  It's fine, except we can't tell who else is on the phone.  
We've muddled by so far, but in 2-3 months our office is moving to a two 
story layout.  No longer can I peak out and see if someone's on the phone. 

I know you can buy upgraded phones that show busy status for all the 
phones...but really, hardware? 

Is anyone aware of a desktop application one could run that lets me see 
on my computer screen who's busy and who's not?  Google knows nothing :).
