HI,
Thanks for the consultation varun appreciate it.
But,my primary problem is concerned with adding port to conference bridge
using pjmedia_conf_add api where i am getting segmentation fault......
so,yesterday i tried a different way round for conference bridge and it
worked using the following
*
pjsua_conf_connect(ci.conf_slot,pjsua_call_get_conf_port(call_ids[i]));
pjsua_conf_connect(
pjsua_call_get_conf_port(call_ids[i]),ci.conf_slot);
*
i was able to confrence call and detach them....
However when more than 4 users call the 5th user gets a busy tone 486 busy
here.
I wonder why,does anyone has any idea about this and how could we increase
the number of users conferencing
Also if conference can be achieved by the following method mentioned
above.Then,what is the use of creating a conference bridge and adding ports
to it to conference calls.
Thanks in advance.
John Smith.
