Hi, using on Debian Linux box latest version of PJSUA. Just wanted someone to confirm this, the --thread-cnt=N option with PJSUA softphone , is this so that one can receive multiple calls simultaneously. For example the callback function static void on_incoming_call(pjsua_acc_id acc_id, pjsua_call_id call_id, pjsip_rx_data *rdata) if i have 10 accounts registered, will this callback be called on a different thread depending on the --thread-cnt=N setting. So if i want to answer 10 calls simultaneously do i need to have --thread-cnt=10. 1.Is there any limit to the number of registered accounts, can i set it to 1000,10000 ?? 2. Is there any limit to the number of sip worker threads 3. Regarding the answering of incoming calls, does the --max-calls=N affect this and what is its relation to the number of sip worker threads Thanks
