[Freeswitch-dev] VAD, TALK and NOTALK events

[Anthony Minessale]

The events are fired.
I don't know what you mean by "enabled"

You can either bind an event to a callback
in the load function of your custom module.

or connect to mod_event_socket on tcp
and request "events talk notalk"

void my_event_handler(switch_event_t *event)
{

}

if (switch_event_bind(modname, SWITCH_EVENT_TALK, SWITCH_EVENT_SUBCLASS_ANY, my_event_handler, NULL)
        != SWITCH_STATUS_SUCCESS) {
        switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Couldn't bind!\n");
        return SWITCH_STATUS_GENERR;
    }

if (switch_event_bind(modname, SWITCH_EVENT_NOTALK, SWITCH_EVENT_SUBCLASS_ANY, my_event_handler, NULL)

        != SWITCH_STATUS_SUCCESS) {

        switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Couldn't bind!\n");

        return SWITCH_STATUS_GENERR;

    }

Hi,

>From 
looking 
at 
the 
code 
of 
switch_rtp.c  
I 
can 
see 
that 
VAD 
is 
done 
if
enabled 
in 
the 
sip 
profile 
in 
order 
to 
not 
send 
packets 
when 
there 
is 
no
noise. 
There 
are 
also 
two 
events 
{TALK, 
NOTALK} 
which 
can 
be 
fired 
when 
VAD
kicks 
in, 
nevertheless 
these 
two 
events 
are 
enabled 
nowhere 
(or 
at 
least 
I
didn't 
find 
a 
place 
in 
the 
code 
where 
they 
were 
enabled), 
so 
no 
matter 
if
you 
ask 
for 
them 
you 
don't 
receive 
them.  
My 
questions 
are 
the 
following:

Is 
there 
some 
particular 
reason 
for 
not 
enabling 
these 
two 
events?  
Is 
the 
event 
queue 
easily 
overflowed 
if 
these 
two 
events 
are 
enabled?

Thanks.

Cesar 
Cepeda.
