OD 8.11.08.01
Onecloud AEP/MPP -> Onecloud forward proxy -> Customer on-prem F5 -> Customer on-prem VXML server
The AEP has a launch URL that is on the OC forward proxy
https://vxmltest.glb.avayacloud.com:12345/OTCS/Start
but it changes to the localhost.
https://itest1.corp.com/OTCS/s1020_ppOTCSGreeting
That won't work as Onecloud only knows about the F5 behind the proxy vxmltest.glb.avayacloud.com, not the individual instance itest1.corp.com.

Then the application attempts to invoke another servlet called RAM, which is used to create VXML pages for WAV files, but somehow the URL is changed and all processing stops.
