Here goes. VPU's store recordings in .r24 format. These get assigned a name generated by the AVDAP software you can't control (like 26.r24 for example). These associate with a number in DB programming (like 500 for example). Here are the important parts:

1. In DB prog, choose an unused recording number to use (ex. 500)
2. Start AvdapMon and make sure you can see events in the window
3. Call in and record "blah blah blah" for exactly 6 seconds on greeting number 500.
4. AvdapMon will show you the filename it assigned to the physical file (ex. 26.r24).
   
   Now you know the file to pick on.
5. Extract the attached zip file. Take the file "ringback.r24" and rename it to match the filename from step 4.
6. In Explorer go to \avdap\db\rcrdings
7. Copy out the file named in step 4 somewhere safe
8. Copy in the renamed attached file overwriting the original.
   
   Almost done.
9. Create a new Call Routing Announcement (ex. 2520)
10. Assign greeting number from step 1 to the day and night fields.
11. Program the destination email address accordingly.
12. Set the digit translation timeout to transfer to the desktop extension.
13. Kill the Auto Attendant Transfer Prompt on the mailbox associated to the extension in step 12.
14. IC the CRA from step 9. Do you hear ringback? You should hear the normal double IC ringback followed by 1 full cycle. Outside callers will only hear the full cycle.
15. Point the DID to the CRA added in step 9.
    
    DONE!!!

Now callers will dial DID xxx-xxx-xxxx, hear a fake ringback tone (from the work completed here) and if no fax tone is detected by the CRA the call will transfer to the desktop extension as a voice call. The first ringback tone should be enough to trick older fax machines to begin transmitting. You will probably want to experiment with the name of the CRA as it will show up as the transfer source on display phones for voice calls.

Honestly, this is how we solved the Tech Support CNG nonsense for a lot of years! The beauty is callers never know their call was stalled one ring because this r24 sounds so close to Telco ringback that only Telco jerks like us will know it's just a bit off!

Let me know if you need more explaining!
