Has anyone else ever received a "Server Unreachable" message when placing a voice call?
This happens when I attempt to make a call to a single phone number. The phone number belongs to a cell phone that has Google Fi service. When I attempt to make a phone call to this number, it rings once on both ends, and then the call ends. When the call ends, I receive a "Server Unreachable" message on my phone display. I do not have an issue making voice calls to any other phone numbers.
I contacted Visible support. They had me perform the usual steps (reset network connections, reset SIM, restart phone), but none of those suggestions helped. I searched some forums, and there were some mentions about toggling advanced calling features under network settings, but I don't appear to have that functionality on my Google Pixel 5.
I battled with Visible Support for 2 hours today, but I finally got them to take ownership of this issue.
At this time, Visible customers cannot call Google Fi customers. Google Fi customers can call Visible customers though. I was able to confirm these findings through testing with 3 Visible customers and 2 Google Fi customers. Not an exhaustive test, but that was all I could pull together from my personal network.
Sounds like this issue is affecting many users trying to make calls from Visible to Google Fi.
