Hi all,

Suppose you have an external SBC that you wish to use for outbound calling to 
an ITSP.  You of course need to create a "SIP Trunk"-type Gateway, which will 
be used by one or more Dial Rules.

But you first need to create an Unmanaged SBC Route for the external SBC, so 
that you can select it as the "SBC Route" when creating the SIP Trunk.  (If you 
use the "None" SBC Route during creation, you end up with a "pure" SIP Trunk, 
and cannot afterwards choose an SBC Route for it.)

As far as I can tell, the only purpose of an Unmanaged SBC Route is to get an 
(otherwise "pure") SIP Trunk to send INVITEs via a particular address (and 
maybe port), instead of the request-uri's domain.

That sounds exactly like an Outbound Proxy...

Could we replace the "Unmanaged" SBC Route with Outbound Proxy and Outbound 
Proxy Port settings on "pure" SIP Trunks? 


By the way, these threads relate to http://track.sipfoundry.org/browse/XX-8137 
Add "ITSP" wizard - predefined simplified workflow


Thanks.
