7.8 Modifying Default Call Progress Analysis Tone Definitions on DM3 Boards

On DM3 boards, call progress analysis tones are maintained in the firmware on a physical board

level and are board-specific. More information on tone definitions is provided in the following

topics:

•API Functions for Manipulating Tone Definitions

•TONE_DATA Data Structure

•Rules for Modifying a Tone Definition on DM3 Boards

•Rules for Using a Single Tone Proxy for a Dual Tone

•Steps to Modify a Tone Definition on DM3 Boards

7.8.1 API Functions for Manipulating Tone Definitions

The following voice API functions are used to manipulate the default tone definitions shown in

Table6, “Default Call Progress Analysis Tone Definitions (DM3)”, on page 57 and some, but not

all, of the default tone definitions shown in Table5, “Special Information Tone Sequences (DM3)”,

on page 54.

Note: Default SIT definitions can be modified, except for the following SIT sequences: TID_SIT_ ANY,

TID_SIT_IO, TID_SIT_NC_INTERLATA, and TID_SIT_RO_INTERLATA.

dx_querytone()

gets tone information for a specific call progress tone
