I have done a similar type of load test but the approach was different. No scripting. But I did use pjsua library for it's convenient features. If you are going to send 4 calls at a time load should not be an issue with pjsua's high volume issues. I used pjsua.exe as a guide for how to setup the code. I only got to 93 simultaneous calls because of the pjsua library usage. And my calls where several minutes long. But I was also testing the play/record/get digits functionality presented. I also only used G711ulaw. It takes some work to get it right. Biggest issue you will face if your goes like mine: deadlock. Watch what you do in a pjsip callback function. You don't want anything that last longer than 200ms because in the timeframe pjsua_hangup() will give you a 70009 error if it can't get to the pjsua mutex. Best solution I have found is to queue up the callback function data and handle the event elsewhere. Because in a lot of the callback functions like on_incoming_call() you are called from the pjsua thread with a double lock on the pjsua mutex. Good luck.
