Am I the only one having issues Resound Linx?

This all sound that great thing to take up with the vendor of Resound Linx and not Apple.

Re: "I have to disconnect my iPhone to accept a standard landline at home or work."

Can you elaborate?

I am not following why you would need to disconnect your hearing aids from your cell phone before you answer a landline phone. Are your LiNX also connected to your landline handset? If not (and it would be surprising if they were connected to your landline handset), you should be able to just ignore the iPhone and answer the landline handset.

The delay between "I want to answer my phone with my LiNX" and actually answering the phone is one reason why I opted away from the LiNX. I realize that might not be an option for you.

Given my personal experience with both the ReSound LiNX and Starkey Halos paired with my iPhone, i can confirm that the interplay between both hearing aids and the iPhone is far from perfect. However, I don't think it is more Apple's problem than it is ReSound or Starkey. Apple has developed technical and programming interfaces to work with a large universe of Bluetooth devices. Consequently, the responsibility for connecting really relies on the device manufacturers to craft devices that meet the connectivity standard as it is defined. That hearing aids experience struggles there doesn't surprise me. The miniaturization of circuitry and the functionality they can pack into very small devices is astonishing.....but also leads to compromise as any other micro-miniature device would have compromises.

My more immediate concern for you is that you have been told that you must disconnect your hearing aids from your iPhone before answering a land line handset. That doesn't sound right.
