Conference between internal IP Phones & outside PSTN Phones

Hi all, I would like to enable conference between our internal  IP phones and outside PSTN phones. Is it possible to make conference between PSTN phones and IP Phones ? Will deployment of  DSP modules bring these feature to our network ? Kindly note that we are using CUCM 7.0 and voice gateway 3900 series. All the helping hands are apprecaited and thanks in advance.

Sure, build either hardware bridges on GW or utilize CM conference bridges, keep in mind software CM bridges only support g711 codec.
