Using FreeTDM Variables
1. User application sending variables or raw buffer to FreeTDM
==============================================================
The User can include a ftdm_usrmsg_t before sending an event to freetdm.
example #1a - Making an outbound call:
--------------------------------------
To make an outbound call:
ftdm_usrmsg_t usrmsg;
/* Attach variable to usrmsg */
ftdm_usrmsg_add_var(&usrmsg, "isdn.prog_ind.descr", "inband-info-available");
ftdm_channel_call_place_ex(ftdmchan, &usrmsg);
example #1b - Adding a variable:
--------------------------------
When using ftmod_sangoma_isdn, user want to specify progress indicator inside PROCEED message.
ftdm_usrmsg_t usrmsg;
/* Attach variable to usrmsg */
ftdm_usrmsg_add_var(&usrmsg, "isdn.prog_ind.descr", "inband-info-available");
/* Request FreeTDM to send a PROCEED msg */
ftdm_channel_call_indicate_ex(ftdmchan, FTDM_CHANNEL_INDICATE_PROCEED, &usrmsg);
example #2 - Setting raw data:
--------------------------------------------------------
When using ftmod_sangoma_isdn, user wants to transmit a custom Facility IE, inside a FACILITY message.
ftdm_usrmsg_t usrmsg;
uint8_t *my_facility_ie = ftdm_calloc(1, 200); /*memory has to be allocated using ftdm_calloc !! */
unsigned my_facility_ie_len = 0;
/* Fill my_facility_ie with custom data here */
my_facility_ie[my_facility_ie_len++] = 0x1C; /* Q.931 Facility IE ID */
my_facility_ie[my_facility_ie_len++] = 0x03; /* Length of facility IE */
my_facility_ie[my_facility_ie_len++] = 0x01;
my_facility_ie[my_facility_ie_len++] = 0x02;
my_facility_ie[my_facility_ie_len++] = 0x03;
ftdm_usrmsg_set_raw_data(&usrmsg, my_facility_ie, my_facility_ie_len);
ftdm_channel_call_indicate(ftdmchan, FTDM_CHANNEL_INDICATE_FACILITY, &usrmsg);
/* FreeTDM will automatically free my_facility_ie */
2. User application receiving variables and raw buffer from FreeTDM
==================================================================
example #1 - print all variables received from FreeTDM
------------------------------------------------------
/* Inside event call-back function */
ftdm_iterator_t *iter = NULL;
ftdm_iterator_t *curr = NULL;
const char *var_name = NULL;
const char *var_value = NULL;
/* Read all variables attached to this event */
iter = ftdm_sigmsg_get_var_iterator(sigmsg, iter);
for (curr = iter ; curr; curr = ftdm_iterator_next(curr)) {
ftdm_get_current_var(curr, &var_name, &var_value);
fprintf("Call Variable: %s=%s\n", var_name, var_value);
}
ftdm_iterator_free(iter);
example #2 - accessing a specific variable
------------------------------------------
/* Inside event call-back function */
char *string = NULL;
string = ftdm_sigmsg_get_var(sigmsg, "isdn.prog_ind.descr");
if (string && *string) {
fprintf("Progress indicator:%s\n", string);
}
example #3a - accessing raw data
-------------------------------
/* Inside event call-back function */
ftdm_size_t len;
uint8_t *mydata;
if (ftdm_sigmsg_get_raw_data(sigmsg, (void**)&mydata, &len) == FTDM_SUCCESS) {
/* raw data is available, do something with mydata here */
}
/* Once this function returns, raw data will be free'd inside FreeTDM */
example #3b - accessing raw data
-------------------------------
/* Inside event call-back function */
ftdm_size_t len;
uint8_t *mydata;
if (ftdm_sigmsg_get_raw_data_detached(sigmsg, (void**)&mydata, &len) == FTDM_SUCCESS) {
/* raw data is available, do something with mydata here */
}
:
:
:
/* User owns raw data and is responsible for free'ing it*/
ftdm_safe_free(mydata);
