as the title says ... for me it's been about 1 month now i have noticed that some callers don't even hear a ring tone when they call me. on my end i hear about 2-3 rings tops, as i accept the call to say hello the call disconnects. verizon had me do an activation (*228), that didn't resolve it. today i called in again and they changed my default ring time from 20 sec. to 30 sec. before a call goes into voicemail. so far, the destinations that have called me and experienced this issue say the calls are going thru fine, on my end i am hearing my phone ring 6 times before it goes into vm. anyone else experience this issue ? i asked about network and tower issues, but they said they had no issues.
