I'm having no ring issues when the cell number is dialed (Holiday, FL). If the caller leaves a message there's not notification of message or missed call. The issue seems related to some period of inactivity on the cell number, perhaps when inactive on WiFi. I've noticed this several times in the morning, but it just happened this afternoon. I have a Moto e5 Play.
This afternoon I called the cell number twice from Google Voice. No ringing heard in the calling phone or from the cell. After some seconds of silence the cell voicemail greeting was heard. I left myself a short message each time. After a couple minutes no message or missed call notice had popped up on the cell.
Next I called another Google Voice number which rings the Hangouts app on the phone. The Hangouts app rang and lit up the phone. (This is not Google Voice forwarded to cell number.) I hung up leaving no message.
Immediately after hanging up the desk phone, the Moto popped up notification of the missed Hangouts call. That notification was immediately followed by notifications of the two cell messages. No missed call notifications.
How do we get the cell number to ring every time regardless of how long it has been since the number was last used?
