Help Speaker phone keeps turning on (x10 mini pro- firmware2.1)

[sin.aiz]

I am having problems with the speaker phone of x10 mini pro. When ever I pick a phone call it automatically turns on the speaker phone and I have to manually close it. Or if that doesn't happen, it keeps switching it self from speaker to normal.

Does anyone knows what the problem could be ?

I have updated the firmware to 2.1 and I dont remember having the same problem in 1.6.
