An outbound proxy receives requests from a client, even though it may not be the server resolved by the Request-URI. It's like setting a HTTP proxy for your browser which will ensure that all requests go through it.
In Eyebeam, if you: * Specify a domain * Enable the 'Register with domain' * Enable the 'Use as outbound proxy' * Disable 'Manual Over-ride' It implies that whatever you specify in Domain would serve as REGISTRAR (outbound proxy is not enabled until you specify the Host). All requests (REGISTER, INVITE etc) will be sent to whatever you specify as 'Domain' However, if you * Specify a domain * Enable the 'Register with domain' * Enable the 'Use as outbound proxy' * Enable 'Manual Over-ride' & Specify a host All requests including REGISTER and INVITE will be sent routed via the outbound proxy (to REGISTRAR or proxy depending on whether the request was REGISTER/ non-REGISTER). My first issue is why REGISTER message was sent to not proxy but outbound server? I think it should be sent to proxy server, right? >> Your assumption is incorrect. All the requests would be sent to outbound proxy. If a SIP phone could be configured with register and proxy server simultaneously, the Request-Uri of REGISTER message should consist of register server domain and sent to register server, and the INVITE Request-Uri should include proxy server domain and sent to proxy server, right? Any Request-Uri couldn't have outband proxy server domain? >> REGISTER will be sent to outbound proxy, request URI will contain @REGISTRAR. The outbound proxy will forward the request to REGISTRAR. Similar processing takes place for INVITE. I hope this helps.

I set up three SIP servers as respectively register, proxy and outband proxy server whose DNS names are register.test.com, proxy.test.com and outband.test.com. Then I used eyebeam phone to do some tests as follows: Firstly, I configured "Domain" with proxy.test.com, enable "Register with domain" && "Use as Outbound Proxy" and disable "Manual-Override", REGISTER and INVITE messages were sent to proxy server by eyebeam phone and their Request-Uris were proxy.test.com. Then I set "Manual-Override" with outband.test.com and kept the other aboved configurations, REGISTER and INVITE messages were sent to outband server and their Request-Uri were still proxy.test.com. My first issue is why REGISTER message was sent to not proxy but outbound server? I think it should be sent to proxy server, right? If a SIP phone could be configured with register and proxy server simultaneously, the Request-Uri of REGISTER message should consist of register server domain and sent to register server, and the INVITE Request-Uri should include proxy server domain and sent to proxy server, right? Any Request-Uri couldn't have outband proxy server domain?
