CUBE not forwarding SIP 480 to CUCM

Hello,

We have a Cisco 2801 ISR running CUBE that is not forwarding a SIP message back to CUCM and it just sends another INVITE to the provider. Here is the SIP message received from the provider side when the called party is not answeringthe call:

Received:

SIP/2.0 480 Temporarily Unavailable

From: "XXX" <sip:XXX@XXX>;tag=9AD3C-986

Timestamp: 1347734366

To: <sip:+40XXX@XXX>;tag=SDgovm999-90b73a4c-CC-33

Call-ID: 823CCA1F-FE9B11E1-8007D629-B1B2F6C4@XXX

Via: SIP/2.0/UDP XXX:5060;branch=z9hG4bK02268

CSeq: 101 INVITE

Reason: Q.850;cause=19;text="No answer from user (user alerted)"

l: 0

P-Charging-Vector: icid-value=88a8a032701dfc19b9e32b4408a39ea9

After this message CUBE is just sends another invite to the ITSP without even notifying CUCM.

I tried multiple IOS images and the behavior is the same.

Any help will be greatly appreciated!

KR,

Alex.

Here is the voice service voip config:
