You should enabled SIP inspection on the firewall; that will take care port openings (for both signalling and media) and SDP headers.
In addition to that, for incoming call establishment, you should allow SIP signalling ports (TCP/UDP 5060) and define the corresponding static NAT entries to point to your CUBE (if CUBE is behind NAT and not in the DMZ).
