Hi, what could be the maximum simultaneous calls can asterisk do? i read about the asterisk business edition review[1] and it can only handle 120 simultaneous calls? i'm using 1.2.x branch of asterisk and i use more or less 90 simultaneous calls.

We had stability issues for a long time, but using weights on the queues was the needle in the haystack that was causing our problems. After removing them, our only failure in the past month has been a single segmentation fault. We are running Asterisk Business Edition. I can't find a quote on Digium's website about their licensing limits, but the site you linked actually quotes up to 240 calls. Our case is not the norm, because we have a special agreement with Digium allowing us to have larger licenses. Note that the use of ABE isn't a necessity for handling this many calls. The stable releases of the open source version perform well, but they don't have any support attached to them. Handling this many calls requires eliminating as much overhead on the Asterisk server as possible, running on high-capacity hardware, and troubleshooting the problems that inevitably arise.

People reports all kinds of numbers above 120. The answer partially depends on your hardware. "Simultaneous calls" can also mean very different things under different circumstances, as the page will tell you. If there is no transcoding/NAT'ing/in-band signaling, simultaneous calls can mean SIP set-ups only. You can see extremely high numbers even on ancient equipment. If everything is in-band and you are using CPU-intensive CODECs, the number will drop sharply. It also varies with types of channels, i.e., whether you use PSTN, IAX, SIP, H.323. But still, I don't think 120 is any limit. Yuan Liu
