Hi Ron, If you're using realtime each Asterisk server will know where every user is irrespective of which Asterisk server they registered on. The problem is NAT, if a client is behind NAT and registers on server 1 then server's 2,3 & 4 are unlikely to be able to get through to it. Last time I lookedthe Asterisk realtime engine doesn't record which server an account registered on in the database so the only option I can think of would be to forward an incoming call for a user to all 4 of your Asterisk servers that way the call will get through but if they are not behind NAT they'll get 4 incoming calls. Bascially it's messy using the set up you've got. What you really need is a SIP Proxy (assuming you're using SIP, if not it's even trickier). The SIP Proxy could load balance requests across your Asterisk servers. For calls destined for your users you can use the outboundproxy field in the sippeers table, by setting it to the IP address of your SIP Proxy server you can get Asterisk to forward all requests for a SIP account through the proxy (there is also an outboundproxyport setting but avoid it as it's been broken forever). There are a few gotchas with a SIP Proxy the main one being transfers. But if you can get away with not allowing transfers then you are best to do so as the CDR's Asterisk produces are wrong anyway.
