ivr_mixed_menu()

int ivr_mixed_menu(int call, IVRMIXEDPROMPTS *prompts, int numprompts, int allow_interrupt, int max_digits, int timeout, char termchar, int clear, IVRDIGITS *ivrd)

The ivr_mixed_menu function plays a series of menu items and retrieves the digits from the specified call. The menu items can either be text or wave files.

Parameters

int

call

Specifies which call to retrieve digits from. It can be one of the following values.

CALL_PRIMARY: Collect Digits from the Primary Call
CALL_SECONDARY: Collect Digits from the Secondary Call

IVRMIXEDPROMPTS *

prompts

Array of IVRMIXEDPROMPTS structures containing the pathnames or text of the prompts to play.

int

numprompts

Number of prompts in the prompts array.

int

allow_interrupt

Specifies if a digit can interrupt the prompts. It can be one of the following values.

NO_INTERRUPT: Do not allow prompts to be interrupted by a digit
INTERRUPT: Allow prompts to be interrupted by a digit

int

Example

IVRMIXEDPROMPTS prompts[4] = {
{PROMPT_WAVE,"D:\\sounds\\Swelcome.wav"},
{PROMPT_TEXT,"This is a text prompt."},
{PROMPT_WAVE,"D:\\sounds\\SGoodbye.wav"},
{PROMPT_TEXT,"Another Text Prompt"}
};

IVRDIGITS ivrd;
if(ivr_mixed_menu(CALL_PRIMARY,prompts,4,INTERRUPT,1,15,'*',NO_CLEAR,&ivrd) != IVR_SUCCESS){
 ...handle error;
}
