Why is IAX demanding so much cpu load?
Which Asterisk version are you running? There was a specific version (1.4.20 I think) that had made IAX super-expensive. The most recent versions of asterisk _should_ have IAX being roughly equivalent in CPU usage as SIP Incidentally if anyone has comparative numbers for IAX vs SIP on 1.6 betas (or hyper-recent 1.4) I'd love to have them for a talk I'm doing at astricon.
