[OpenSBC] SipX<=>OpenSBC: inbound route doesn't work

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

I've configured SIP Trunk on OpenSBC. Calls from sipX to PSTN over sip provider are working well. But when I try to call to my external PSTN number (must be routed to sipX number) I got an Internal error after vey long timeout. 

Seems OpenSBC doesn't route calls to sipX. 



Help me pls!



My configs: 



SBC Mode:  B2BOnlyMode



Interface: sip:*:9000



B2BUA Route: [sip:44*] sip:provider.org;sip-trunk=true 



<xml>
<siptrunk trunk-name="provider.org" route-set="provider.org" sip-domain="provider.org" expires="20">
<trunk-accounts>
<account user-name="44444444444" auth-user-name="44444444444" auth-password="mypass" inboundroute="sip:10...@si..." expires="3600" />
</trunk-accounts>
<transient-accounts>
<account user-name="44444444444" auth-user-name="44444444444" auth-password="mypass" inboundroute="sip:10...@si..." />
</transient-accounts>
</siptrunk>
