I have been using iPhone(s) and Resound Linx 961 for 5 years and their BT direct connectivity to the iPhones was very good, with some hiccups of disconnecting if too far from the phone but reasonable performance.
I just updated my iPhone 6 to iOS 11.1 and now the response time to pass the call or media audio to the HA is unacceptably long to a point of losing a call because I can’t hear the people on the other side for 15 to 30 seconds while the phone streams to my H Aids.
I submitted a claim to Apple’s Disability line tech support and they could not find a problem yet, we did the typical reconnect, repair, delete all settings etc. to no avail.
To solve the issue momentarily I disable call routing to the HA and use the speaker but is annoying and I must be in a private room to talk.
If anyone had this issue and resolved it please let us know.
