Yes, but that doesn't explain why you are routing the INVITE further even if you gave a 500 reply back. Why is this?

I'm not sure if there is any problem in using ropology_hiding with callcontrol, if there is I'm not aware of it, but other than that, I don't see any problem with those steps.

Please do check that misrouted INVITE, I think it's the actual cause for this.
