Hello there, I recently purchased the RUTX12 but It seems to fail to be able to "seamlessly" switch over, both sims are active and working but once the main sim1 modem loses connection or goes to low signal strength the video call drops and wont reconnect until 4-5 seconds later, I even set the interval for all the pings to 1 and still same issues, I bought this router so it can seamlessly swap back and forth seamlessly without dropping connections and it doesn't seem to do that? Thanks
