I've seen that problem before " Icm Dir Prgm Clr". At the risk of being diagnosed with a brain cramp, I believe getting rid of it might be as simple as pressing the "clear" button on the phone. Other might chime in on that if I'm wrong. It's been so long since I've seen it.

When you,say external paging is not working, how were they accessing it. One touch key, function key, dialing a feature code?
