Anyhow, with your hardware configuration the number should be much higher. You can use allow_trusted() (see http://openser.org/docs/modules/0.9.x/permissions.html). Another option is to use an special AVP per user and avpops to check it (see http://www.voice-system.ro/docs/avpops/ar01s08.html#ex_trusting). It is up of your billing system and what are you more familiar to. I haven't played with such configuration, maybe some other users can help you. But as far as I know, mediaproxy supports distribution so you can add a new system when your bandwidth is exhausted. The best approach is to have each server (sip, database/radius, rtp relay, media server) on different systems and replicated in active-passive modes so you avoid single point of failure. Daniel
