Okay, so we are generating a PRI an an AS5400 media gateway and delivering it to an IAD2400 at the customer site. There are three channels on the PRI, which is reflected in the trunkgroup status.
When we make three calls to the customer, everything works fine. All three calls go through as they should and show up as they should.
The thing is, when we place a 4th call, instead of getting the expected busy signal, the AS5400 media gateway gives a beep and disconnect. If no channels are available, shouldn't the media gateway be generating a busy signal? Or do we have to specifically tell it to do that in some way?
