Sangoma P320 phone and PM200 Sidecar . Sidecar boots but is blank

[pbxalerts]

Sidecar firmware PM200 4_16_2 and PM200 4_15_4 tried.
Template is setup for the PM200

the extension has been edited to have the expansion module set to pm200-1

I can tell the sidecar is on after it boots. none of the buttons work though. and the screen is blank.

The PM200 isn’t supported by the P320 model telephone. It’s supported by the model P330 and model P370 telephones.

Took me hours to find it. but, I finally did. wish it was more well documented.
