Charging Connect Fee for every call attempt (including FAILURE/zero duration)

Hi!
I am experiencing difficulties configuring Connect Fee. For some reason, i need to charge a fixed fee for every call attempt:

FAILURE, duration = 0 –> charge Connect Fee
SUCCESS, duration = 0 –> charge Connect Fee
SUCCESS, duration > 0 –> charge Connect Fee + traffic

According to the documentation ( Routing | Yeti Switch )
“Change Customer’s and Vendor’s balance … in case of successful call with non-zero length (Step 12.4)”
So balance is changed only for successful calls with non-zero duration, and Connect Fee is never applied to failed or zero-duration calls.

I tried to force failed attempts to be treated as successful by updating disconnect codes, but with no effect.

UPDATE class4.disconnect_code         
SET                        
  success = true,
  stop_hunting = true
WHERE code = 603;

Questions:

Is this a design limitation of Yeti billing?
Is there any way to charge a fixed fee per attempt (including FAILURE)?

Thank you!

Currently there is no such feature, it requires development.
