Sample Display
The following output shows that the call has been accepted and that the system is now checking for
incoming dial-peer matches:

The following output shows that a DSP has been allocated to process the call and indicate to the higher
layer code:

The following output shows that the higher layer code has accepted the call, placed the DSP in dual tone
multifrequency (DTMF) mode, and collected digits:
