Hi,
I'm just trying to rephrase 'examining return code of
pjsua_call_get_info()'. Whenever a call on pjsua_call_get_info()
returning non-PJ_SUCCESS, the call_info contents will be invalid, so
the condition of (call_info.state == PJSIP_INV_STATE_INCOMING) will
always be false, this might have caused incoming_calls_count()
sometimes returning 0, which is suppossed to be 1.
Regards,
nanang
