I don't know if it is possible using AddressBook (I didn't see anything in it's AS dictionary and I haven't checked it's Obj-C framework yet), but you connect to it as a serial port and dial it with AT commands. I know Jirka was looking into this.Originally Posted by MacUsers
So you could use either the AS or Obj-C interfaces to AB to get the number you want, then use the serial interface to actually dial the phone.
I have some old code using the Obj-C framework to update AB entries based on the results of a web query. It's relatively straight forward so it should be easy enough to follow even though I don't think there are any comments to speak of in it
