Bluetooth headset for MacBook Pro

[Yoni Golden]

I have Jabra BT3010 Headset, which I'm using for Skype conversations on my MacBook Pro. Unfortunately, when I'm using the headset people can't hear me, altho I hear them clearly (usually).

I went to the Apple store where I live and they told me it's probably a software problem.

Did someone have or had the same problem? or familiar with a solution?

I'm using a MacBook Pro 15" 2.4 (OS 10.5.6)
