I'm trying to setup a 3pcc phone with a local asterisk server (controlled by freepbx). Things seem to be working, but my log is full of bad event errors from the phone:

I can't find what feature is causing the subscription trigger, or what can be done on Asterisk side in order to handle "as-feature-event". I don't want to needlessly wear out the SSD with the logs and would prefer to understand & address the issue.
Any assistance is greatly appreciated.
