FreeSwitch is very capable of handling high call setup loads... The question is what do you consider high setup loads? Where it is true, OpenSER/SIP/whatever its called this week can handle a much higher packet per second load then freeswitch, freeswitch on the other hand is capable of handling much more call volume then asterisk... Certain people hate when I quote numbers but I have personally deployed FreeSwitch on projects that handle (per FS Box) > 500 calls/sec (that's 2 leg calls) and in excess of concurrent calls... The real question is not can FS hang, but what at what level do you call 'high volume'... What I call high volume is a telemarketer running at 2500 calls/sec and peak concurrent channel usage in the 10,000 to 15,000 channel range K

----SNIP So to get back to my original question, if FS can handle a significantly higher number of call setups, then perhaps I don't need OpenSer, that was the thrust of my post. ----SNIP
