Hi All, I have successfully implemented conference calling using PjSIP with 3 mobiles.But i am unable to increase the count further. So to check how many calls are allowed i used, pjsua_call_get_max_count(); Which in turn returns th maximum call allowed. I am getting value as 2 (two) only. How can we increase the max call allowed count? Under PjSIP\pjsip\include\pjsua-lib\pjsua.h, the max_calls value is returned when ever we call the method pjsua_call_get_max_count(); /** * Maximum calls to support (default: 4). The value specified here * must be smaller than the compile time maximum settings * PJSUA_MAX_CALLS, which by default is 32. To increase this * limit, the library must be recompiled with new PJSUA_MAX_CALLS * value. */ unsigned max_calls; I even recompiled all the libraries by changing the count to 10(ten) and tried, but unfortunately i am getting max call count as 2 (two). So, how can i increase max_call count? How many calls can be added in a Single conference? Please some one help me... -- Thanks And Regards, Srivatsan.D,
