Hi

enum pjsip_inv_state provide the different types for INVITE session
management. In Call object, onCallState notify on SipEvent the following
events:

• PJSIP_INV_STATE_NULL
• PJSIP_INV_STATE_CALLING
• PJSIP_INV_STATE_INCOMING
• PJSIP_INV_STATE_EARLY
• PJSIP_INV_STATE_CONNECTING
• PJSIP_INV_STATE_CONFIRMED
• PJSIP_INV_STATE_DISCONNECTED

I get PJSIP_INV_STATE_CONFIRMED before PJSIP_INV_STATE_EARLY, so I think it
is not possible to be notified before.

Invite session reference:

They sometimes accept calls immediately and play some kind of music-on-hold
in which case you're not able to directly find out when the actual party

Hi,
it's called early media, so the PBX/C5 Softswitch has to return a "183" status as stated in the RFC.
Draft:
https://tools.ietf.org/html/draft-rosenberg-sip-early-media-00

So, the call state confirmed is the thing you're searching for.
Snippet to demonstrate the "confirmed" state: (on_call_state callback using pjsua).
Callback:
https://www.pjsip.org/pjsip/docs/html/structpjsua__callback.htm#a8029ac58404a39067691a1530a2b585a

Snippet taken from my call quality check program, where the wav file starts when the call has been confirmed:

/*

• Handler when invite state has changed.
  */
  void on_call_state(pjsua_call_id call_id, pjsip_event *e)
  {
  pjsua_call_info call_info;
  pj_status_t status;

PJ_UNUSED_ARG(e);

pjsua_call_get_info(call_id, &call_info);

if (call_info.state == PJSIP_INV_STATE_CONFIRMED) {
if ( pj_stristr(&call_info.remote_info, &app_config.remote_contact) != NULL ) {
status = pjsua_conf_connect(app_config.wav_conf_port_id, call_info.conf_slot);
if (status != PJ_SUCCESS) program_exit("Error connecting wave port to call slot", status, CRITICAL);
}
}

Hope that helps.

Best regards

Franz

Yes, I use asterisk as PBX, but my scenario is very simple. Incoming calls
call to an agent after answer. I have only an agent so, if agent is busy
with another call, then the music-on-hold play.

EARLY state of the INVITE session has nothing to do with early media.
It just means you've got a response with a To tag, as described in the
pjsip docs.
You can have early media in EARLY state, but it's actually a separate
thing.

For reference, see this:

Hi Andreas,
actually i'm not confusing things because i replied to your info, that music can be played before the actual confirm happens.
This is called early media and will be replied with a 183 Status code.
I'm not refering to the INVITE state though.
It's not supported for PRI/ISDN multis but for newer SIP implementations (asterisk).

Best regards
Franz
