I have a client on a PRI from Charter Fiber they have switched from pots line service to a full PRI. One of their departments (originally had only 4 pots lines) was being overrun with calls I programmed call by call and 4 GCO keys limited the number of inbound calls to 4 that took care of the incoming call volume problem but now on the 5th call we are getting an intercept from the carrier saying "your call can not be completed at this time" the customer wants a simple busy signal. does anyone know what layer 3 message the CIX 100 R3 sends in this scenario. I'm trying to sound like I know what I'm talking about when I approach Charter
