Is Outbound Proxy for proxy server setup?

[pbxnew]

Another basic question:

 

When creating a Trunk, should I choose Outbound Proxy or SIP Registration if I want to set up this PC as a SIP proxy server?

 

 

TIA.

I would recommend to always use the outbound proxy setting, even if it is identical to the domain name. It just makes it 100 % clear where the request should be routed to. The only exception I see is ENUM, and accepting calls from the wide open Internet - but I guess that is not on you list.

I still cannot get this clear

 

I want to set it up as a SIP proxy server. Must I have username/password configured on Trunk? WHere should I put the SIP proxy server IP? Because the PC has mutiple NICs, I want to use one of the IP as the proxy server IP. The account should be Extension or Auto Attendant, or other choices on the list? And can I put IP instead of phone number somewhere? Does it support IP phone?

If you don't know from which IP address a request will come to the PBX and you want that this request lands on the trunk, then you must not use a outbound proxy. However, then you must make sure that the PBX is able to identify that the call goes to the trunk - see http://wiki.pbxnsip.com/index.php/Inbound_...ifies_the_trunk for more on this topic. The outbound proxy is also the "inbound proxy"...

 

You can make the PBX bind only to one IP address, but you would do that in the port settings of the PBX. See http://wiki.pbxnsip.com/index.php/Port_Setup.

 

You can use static registrations if you want to send a call to a specific IP address when an extension is being called. See http://wiki.pbxnsip.com/index.php/Extension#Registrations for more on this topic. But usually this is not a good idea. Practically all (S)IP phones support registrations.
