OnePlus 5T VoLTE


Has anyone managed to get a OnePlus 5T (A5010_43_19_0731 with OOS 9.0.8) working with VoLTE with Telus?
I've had Telus enable the IMIE for VoLTE; I've set the phone for VoLTE enable and VoLTE preferred.
If you have it working, what else did you managed to get Telus to do and/or what else did you do on the 5T.

Thanks for your attention and thanks in advance for any information you might share.
