I've got a strange problem with my new Galaxy S9+. I forward my home phone (using phonepower voip service) to my cell. Whenever I receive a forwarded call, the S9+ always shows the "forwarded call" tag at the bottom of the home screen but it doesn't always ring or vibrate, just eventually goes to voicemail. About half the time it will ring, and the other half, it just stays silent and shows the "forwarded call" notification. I have Tmo service, but because I get the "forwarded call" notice, it doesn't seem that it would be the service. -I've talked to phonepower tech support twice, and they're convinced their end is handling the forwarding correctly. -I've checked the settings and can't find anything unusual. -I've googled around, and checked the forums here, but haven't found a similar problem or any help. Has anyone had a similar problem and found a solution?
