I dont know who to blame, but we've had the same problem here with our small 
sales team. The sales team (about once a week) will dial a call on their 
analog phones (analog cordless phones plugged into a few SPA-2001s) - they 
press 'talk', dial the #, then immediatly are connected to an incomming 
call... (I use two TDM quad FXO cards to service 8 incomming lines from 
Sprint).

I havnt been able to track it down, and its not reproducable manually...

Anybody have any ideas?
