Hello & Welcome to Just Answer,
Sorry to hear of any issue you may be having with this system & headset.
Panasonic has a Bluetooth Headset "Compatibility Chart" at the following link.
I don't see the H730 on that chart, but I do see the H720. This could be because the H730 is "newer" and has not been tested yet, but I would think the newer model headset would have similar compatibility to the H720.
Do you have a specific issue when trying to get the current handset working? That is, were you able to find the steps to pair the headset, and get any errors during the process?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
