I have the following situation, and can't work it out: I have two sets of the phones on the CCM, first set can call only PSTN numbers, whereas the second calls both PSTN and GSM. So I created two partitions (PSTN-PT & GSM-PT) and two CSS's(PSTN-CSS & GSM-CSS). GSM gateway goes to GSM-CSS, but I don't know how to put PSTN-gateway to two CSS's, both PSTN-CSS & GSM-CSS? The first thing that crosses my mind is to create another partition for PSTN-gateway only, but you can't put a GW into a partition. Sorry if I overcomplicated it, but I hope you get the point...
