The events are indeed fired, but only if the SWITCH_VAD_FLAG_EVENTS_TALK or NOTALK flags are set for an rtp_session. I found no place in the code where those flags are set. That is what I meant by not being “enabled”. I subscribed to the events and received nothing. Then I set the flags on switch_rtp_enable_vad function, and then I started receiving the events. Perhaps there is another way of doing it that I’m missing. Cesar Cepeda.

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; } Anthony Minessale II FreeSWITCH http://www.freeswitch.org/ ClueCon http://www.cluecon.com/ AIM: anthm MSN:anthony_minessale@hotmail.com GTALK/JABBER/PAYPAL:anthony.minessale@gmail.com IRC: irc.freenode.net #freeswitch FreeSWITCH Developer Conference sip:888@conference.freeswitch.org iax:guest@conference.freeswitch.org/888 googletalk:conf+888@conference.freeswitch.org pstn:213-799-1400 ----- Original Message ---- From: Cesar Cepeda <cesar@auronix.com> To: freeswitch-dev@lists.freeswitch.org Sent: Tuesday, February 12, 2008 6:53:03 PM Subject: [Freeswitch-dev] VAD, TALK and NOTALK events 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.
