The easy answer to this is: No. Far too many variables. Not just cpu speed, but cpu cache size, memory type & speed, external interfaces (over a PCI bus/TDM or Ethernet/SIP/IAX) other tasks the CPU might be doing, compile-time optimisations, kernel optimisations, etc. As a generalisation, without transcoding you'll be able to manage 100's of calls on a modern Intel or AMD server platform, but all bets are off when you turn on transcoding, echo cancellation, etc. Gordon _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
