[asterisk-dev] rtp scalability improvement...

[Anton]

I would say that more than one server is not good, when 
there is performance issues only. having processing 1000 
calls/s on fast hardware and good clustering options will 
bring asterisk to a new usage levels. Industry levels. And 
possibly Industry would involve it's developers too. In 
normal case that will lead asterisk to became a monster 
app, able to do most things needed in telephony :)

In the comparisions of price/performace - Asterisk can 
win... but total luck of H323 support kills any advantages. 
MVTS costs $3500 per 30 concurent calls (E1) and I would 
love to replace it with Asterisk even in cost of extra 
servers. But as I said - there is no H323 in Asterisk.

Regards,
Anton
