More than 6 months ago, [I totally have forgotten when], there was a Republic update. Till that time both phones worked over the home Router over WiFi Perfectly.
Immediately after the update, over the WiFi incoming and outgoing calls would not connect to the other parties. We did notice that if the other parties hung on for maybe 30 seconds while not seeming like they were connected [on both their end and ours] then sometimes the connection would be made. We saw others had the same problem, so we tried a fix suggested at the time, however it did nothing to help. Forgot what the fix/fixes were suggested.
Since then, We simply got used to disconnecting from WiFi to make calls. When recieving, we try to disconnect from WiFi quickly, however we find the other party usually hangs up when they don’t hear us, so we just call them back. We are about done with this system, and worry that new phones won’t even help.
