Precedence of local-policy over Route

Hello,

I got stuck. Help me please. SBC receives a request from SA with Route header and applies this Route at once. It even does not look for the local-policy. My stupid question is how to force sipd to apply local-policy instead of installing Route?

Here are the details. S-CSCF forwards SUBSCRIBE to SBC. There are two routes included:

1st Route <sip:ibcf-ims.mnc.mcc.3gpp.org> — this is SBC itself

2nd Route <isc@scscf.ims.mnc.mcc.3gpp.org>— this is SCSCF

Once SUBSCRIBE is received, SBC checks the 1st route (does nothing with it) and then checks and applies 2nd route, i.e forwards the SUBSCRIBE back to S-CSCF, despite the local-policy that I configured with wildcards for the whole source realm. I am going to try to remove both routes manually with inmanip (although I think it will not help) or ask S-CSCF not to send me its own mess.
