Native Interface event delays?

Hi,

I am integrating the native interface in to our application, currently I am only interested in handling OnTalkButtonPressed for answering/releasing calls.

However, i am finding substantial delays(1-3 seconds) in getting the events from the wireless headset. So far i have tested with

a Voyager Pro and a CS520. All the wired headsets seem to respond quickly.

Is this normal for wireless headsets? Any way around it?

Thanks in Advance.
