Fast busy on TDM400P
I'm getting a random fast busy signal after two rings on an incoming ZAP
channel through an FXO interface on a TDM400P. I have a NoOp in the
dial plan showing the callerID. When the random fastbusy happens, no
CallerID is sent. When it works, the CallerID information is sent. Is
this a card issue or a telco issue? I have a very upset client and need
to figure out how to resolve this.
