The Verizon phone User Guide says on p. 22 that by dialing *61 you can set up Priority Call so that you can program a distinctive ring tone for some of your incoming calls/callers. When I try to do this I get an automated voice telling me the service is unavailable. What gives? Or does this fall under the catch-all caveat on p. 1 of the User Guide that "some calling services described in this guide many not be available in your area . . . ." I live in Northern Virginia and my area code is 703. This is a very useful feature and I wish I had it.
