iphone 6 facetme call ringing at both end but no audio after call is accepted, call failure

[iMore Question]

My iphone 6 facetime function was working very fine, all of sudden it is not working.
When I place fcatim call it is ringing at caller and receiver ends, when call is accepted call time counting starts but both sides cannot hear any audio, after sometime call failure notification displayed.
wifi signal at both ends fine. facetime settings ok. ate and time settings on auto.

The Wi-Fi signal may be fine, but that doesn't mean that the internet connection is. Reboot the cable/dsl modem and router on both ends and then try again.
