The default call progress tones are Dial Tone and Ringback Tone; however the
Busy Tone or Reorder Tone will be played instead if the application provides the
CCITT compatible SIGNAL IE by sending either the SETUP_ACK or
ALERTING message (see the cc_SetInfoElem( ) function description for
information on setting the SIGNAL IE). The SIGNAL IE must be programmed
according to the ITU specifications. The firmware will correlate the specified
signal, in the SIGNAL IE, with the appropriate sigType from the template table.
