Does anyone have shareable examples?

I have a CUBE behind a VMwareEdge firewall, performing NAT towards the ITSP.

When I receive an "OPTIONS" from the ITSP, the external ip-address is presented to my CUBE, and teh request is rejcted as shown below.

My CUBE are using 10.190.87.100 for the interface receiving packets from the ITSP.

CUBE configuration attached, "voice class sip-profiles " most certainly flawed.
