Re: [OpenSBC] Can OSBC meet this use case?

[OpenSBC F. <ope...@op...>]

Yest, most definitely.

Start with a fresh config of OpenSBC (just delete your OpenSBC_data/opensbc.ini) and follow these steps.

1.  Set General Parameters/SBC-Application-Mode to "B2BUpperReg Mode" then restart OpenSBC after you click Update
2.  Add [ sip:*@ims.domain.com ] sip:10.0.0.3 in Outbound-Proxies/Outbound-Proxies settings. (This will force all requests bound for ims.domain.com to traverse your proxy)
3.  Put a check on B2BUA-Routes/Route-By-Request-URI

That's it.  If your invite looks as follows, it will reach the IMS network.  This assumes that OpenSBC is treated as if its a normal OB proxy by the calling UA.  You can't treat it as if it's a GW or this scheme won't work.

INVITE sip:us...@im... SIP/2.0
To: <us...@im...>;tag=123
Route: <10.0.0.2;lr>

HTH,
