NO PHONE INVOLVED - I HAVE MY IPHONE IN AIRPLANE MODE.
I CAN INITIATE AND RECEIVE CALLS. AFTER 2-5 MINUTES THE CALL DROPS.
I AM USING LATEST MOJAVE SOFTWARE AND INTERNET CONNECTION IS SOLID WITH LESS THAN 5MS JITTER, LESS THAN 20 MS LATENCY, 160 UP AND 10 DOWN ON COX CABLE. LONG TERM TESTING SHOWS NO DROPOUTS EVER. BANDWIDTH IS 160 DOWN.
IF I CALL BACK, IT IMMEDIATELY CONNECTS AND 2-5 MINUTES LATER IT DROPS.
Thanks for reaching out! We encourage you to take a look into our Support Article about Wi-Fi Calling, which includes details regarding the limitations of the service. If you have any further questions, don't hesitate to let us know!
