Hello, I'm trying to figure out what portions of Asterisk need a lot of CPU time. I thought I read somewhere that a Dual P4 2.something will support approximately 80 calls. Is this based on calls that Asterisk is actively doing voice processing for (say, Zap channels and voicemail)? Would a SIP client going through Asterisk and out an IAX channel be CPU intensive if I kept the codec the same throughout the path? I'm probably not asking very clearly, it's awefully late (err, early) but any pointers would be greatly appreciated. Thanks Matthew

If there is any codec translations, then you would run into some extra overhead.> I'm probably not asking very clearly, it's awefully late (err, > early) but any pointers would be greatly appreciated.Maybe you would do better to ask more pointed what YOU need help with. If you need help with specing out a machine for your installation, then start specing your installation so we can help. -- Steven Critchfield <critch@basesys.com>
if you have 80calls going, its time to think on getting a good dedicated server, switches, for the work and UPS with big batterys also some good power supplie:) Miguel On Fri, 2003-11-28 at 12:51, Matthew Asham wrote:> Hello, > > I'm trying to figure out what portions of Asterisk need a lot of CPU > time. > > I thought I read somewhere that a Dual P4 2.something will support > approximately 80 calls.
