Archos 101 + 3g stick it's possible use it also as a smartphone?

I just received this tablet with 3g stick - i would use it also for voice call not in internet but through the sim because i had a full phone plan with voice and internet -
i know that other tablet like sam.... with a software patch had enabled voice function -
we have to wait for a software upgrade or there is an hardware problem ?
in this case there is another usb modem with this function ?

thanks for your attention
