Simultaneous ring has stopped working on my iPhone 6 since I updated to iOS9 when it became available months ago. At that time, I could answer the call on my iPhone but neither party could hear each other. I spoke to Shaw, Apple, and Virgin Mobile with no results. I activated it again yesterday to see if the issue has been fixed. When my iPhone rings I answer it but the home phone continues to ring and there is no connection. As well, my iPhone brings up the buttons to hold/hang up current call and accept new call or decline new call. It appears to see the original ring as answered and the continuing rings (from same call) as a new call. Has anyone else had this issue and has it been solved? TIA.
