Upload custom ringtone to Poly vvx450

[zackerman]

I'm testing out Zoom phone service, and in the setup process, I'd like to add custom .wav files to the options that users can select from for their ringtone. I uploaded a .wav file via the vvx450's web interface, but once I add the url to the recommended Zoom provisioning server, it gets wiped from the phone. Is there a simple way to create a template that lets me include ringtones for users?

Solved after some digging. 
A user on the Poly forums showed how to format .wav files to work on Poly VVX phones: https://community.poly.com/t5/VoIP-SIP-Phones/Polycom-VVX300-and-custom-ringtones/m-p/83002/highligh...
Building the provision template wasn't too hard once I found the corresponding parameter in the Poly UC documentation: https://docs.poly.com/bundle/ucs-ag-6-0-0/page/r-ucs-ag-sampled-audio-file-parameters.html
After that, it was just a matter of uploading my .wav file to a publicly accessible url, one caveat being that I had to make sure the .wav file name in the url had no special characters, because it messed up the Poly phone. On Zoom's side, the provision template looks like this: 
saf.2 = "https://hostingsitedomain.com/RickAstley.wav"
