I'm using a 202 with Freephloneline but I don't know how to change how many rings are made before it goes to VM. Thanks!
That is not determined by any OBi setting. Look to the FPL account. From https://support.freephoneline.ca/hc/en-us/articles/212430286-Change-voicemail-settings:
You can change your voicemail settings (password, listen menu prompt language, rings before voicemail) by logging in to your account on your computer, choosing "Settings" and then "Voicemail Settings"
