I have 2 handsfree kits installed in my car, (Bury CC9050, Nokia CK-20W) and 1 in my wifes car (Nokia CK-15W).

I have SE K800i and Nokia 6230i, and my wife has K550.

When a call comes in with either of the SE phones, in any of the Handsfree kits, there is a 3-4 second delay between pressing answer button and hearing audio.

Its only with SE phones.

Has anyone else come across this?

Is there a cure?

Thanks
