iPhone 4 issues with Jawbone Jambox

[GregLyles]

Hello, I recently purchased a Jambox from Jawbone to use in my office as a speaker phone. It seems every time I leave my office with my iPhone I have to reestablish the connection when I return to the office. Also, while I was on the phone and not using the Jambox speakerphone, I walked back into the building and lost my phone call - as I walked down the hall I could hear the person on the Jambox asking if I was still there! It seems there was no warning or request transferring the call back to the Jambox - it just did it without prompting.

Any thoughts on this? Should I return the Jambox or is there anything else I should consider?

Thanks!
