Dear Srivatsan,
Thanks for the valuable information. Conference is working fine now. By the
way I'm using asterisk PBX and trying to connect conference. Just look into
the modifications mentioned below and let me know whether I'm doing
correct.
I've inculded the following in extensions.conf file:
[TPS]
exten => rooms,1,MeetMe(arul|bhavani|rajeev)
Also I've included the following in meetme.conf:
[rooms]
conf => arul,bhavani,rajeev
Onceagain thanks for the help.
Thanks & Regards,
- Senthil

<pre wrap="">Senthil,
I suggest to just dial all the calls first and leave rest to take care by
call back methods. Just connect the ports in call back methods and will
work fine.
Here is how i do in my application,
1. Getting the SIP address from user (multiple address).
2. Check the address valid.
3. Make call using each valid address and get the call ID.
4. Rest would be taken care by <b>on_call_media_state</b> call back method.
5. Based on call ID you can track each call and do necessary operations.
Note: You need to make <b>max_calls</b> to 3. Default is 2 in PjSIP.
Suggestion : To have more members in in conferencing, i suggest to try
<b>Asterisk, </b>i have connected upto 15 mobiles to the conference room.
This will help better performance of mobile since audio mixing is happening
in server itself. Also u cannot feel the audio lag.
Here is the code snippet which works fine for me.
1. For each time a call gets active, i am establishing full duplex sound.
/* Callback called by the library when call's media state has changed */
static void on_call_media_state (pjsua_call_id call_id)
{
pjsua_call_info ci;
pjsua_call_get_info (call_id, &ci);
if ( ci.media_status == PJSUA_CALL_MEDIA_ACTIVE)
{
/*
// When media is active, connect call to sound device.
pjsua_conf_connect (ci.conf_slot, 0);
pjsua_conf_connect (0, ci.conf_slot);
*/
pj_status_t status;
pjsua_conf_port_id id[PJSUA_MAX_CONF_PORTS];
unsigned c, i, j;
c = PJ_ARRAY_SIZE( id );
status = pjsua_enum_conf_ports (id, &c);
if ( status != PJ_SUCCESS)
c = 0;
for (i = 0; i < c; i++)
{
for (j = 0; j < c; j++)
{
if ( i != j)
{
pjsua_conf_connect (id[i], id[j]);
}
}
}
}
}
</pre>
