Got several 3102 devices for incoming lines. They're answered by an auto-attendant module which gives a number of possibilities, including ringing all extensions via a ring group. Works ok best I can tell, except that when the phones ring, I see "PSTN 1 - 10002" calling, not the caller ID of the real caller. Not life-threatening, of course, but it would be NICE to be able to see who's calling me. Anyone know how to fix this?
