Hello Ruddy, I would not use Asterisk because it has SIP DoS attack which will crash your system if you are not expert. FreeSwitch is crossplatform (father of Asterisk, Yate and developer minded), it can be used for light to heavy you decide, it supports ARM, 32/64-bit. More then that FreeSwitch community is excellent, when one has problem, 100;s of others jumps back on you to help you out, they share knowledge instead of keep it inside like EVIL. Without community like that you will end up in desert when some problem starts. Thanks Regards -------------- next part -------------- An HTML attachment was scrubbed...
