I am trying to make a CSD call from one phone to the other (using APIs from the etel lib). On the receiving phone, I would like to display the number of the calling side (this number needs to be the CSD number rather than the voice number). What is the best way to go about doing it ?

The following web site details two ways of doing it (one using the etelmm lib and the other one using the Etel3rdParty lib), but I am not sure if either of them would work for a CSD caller number (I know that CTelephony of Etel3rdParty lib does not support CSD calls)

I am using a S60 3rd edition FP2 device (N85)

Any inputs would be most appreciated
