Hi Alaa, I've never tested pjsua with more than about 50 calls but I don't see why it couldn't scale to thousands. If you are using G711 with bridge running at 8kHz then the media processing per call is very light, a single core should be able to handle perhaps 100-200 calls, but I don't know exactly. But if you are using a high def codec you will get far fewer calls. You could create one bridge per core, so for example if using an 8 core server you would create 8 bridges and as calls come in you would assign them to the least loaded bridge. That may be simpler than one bridge (and one media processing thread) per call. I recommend you code up a single bridge answering system using pjsua, and then load test it to see what kind of performance you get.
