multiple Voyager 5200s on multiple iPhones iOS 18.2 no longer pick-up my voice on phone calls

I have an open case  regarding my Voyager 5200.  Without satisfactory solution.

 The microphone no longer works on multiple iPhones.  I have three of the 5200 and all three no longer pick-up my voice while attempting to use them to talk on my phone.  I have upgraded the firmware on all the devices to 517.293 and this does not seem to help.  The iPhones are running iOS 18.2.  

Is anyone using the Voyager 5200 with current firmware installed on an iPhone running iOS 18.2?

  I am very disappointed that these devices no longer work since I rely on them when I am doing my runs and other outside activities.  I'm to the point of not recommending them for use any longer.

I am updating this issue to say that I was able to use the Voyager 5200 to make a recording using the Online Voice Recorder at the 123APPAS website using my MAC and Safari.  So this to me shows a definite issue with the Voyager 5200 working with iPhones using iOS 18.2.  I know it worked with earlier iOS but I do not know when it stopped.

Will HP and the POLY division fix this issue?
