my caller gets busy tone in a single ring and call gets cut
Hi to all,
I'm Shankar, I have iPhone 6 since few months. Last couple of weeks I notice lot of missed call from my contacts but I don't get any phone ring sound/Alert. Though ringtone has full volume not on silent mode anymore. My callers says that when calling me goes a single ring and than cuts automatically. Another friends noticed when he tried second time call connecting after first failure. Please do let me know someone can fix the issues kindly. I'm really sick of this problem. I use Airtel mobile network in INDIA resides in PONDICHERRY.
Thanks in advance!!!
best regards
Shankar
