(I am straying from the original topic, so I changed the Subject.) This is not a standards-related issue, so we can end this thread if someone objects, but I was wondering about the legal ramifications of caller ID. Are there laws in some countries that require the following, or is it just considered good etiquette and/or a market-driven feature? Caller ID to be transmitted if provided by the caller Caller ID not to be displayed to the called party if so requested by the caller ("presentation restricted") Paul Long Smith Micro Software, Inc. -----Original Message----- From: Chris Purvis [SMTP:Chris.Purvis@MADGE.COM] Sent: Thursday, May 13, 1999 8:28 AM To: ITU-SG16@MAILBAG.INTEL.COM Subject: Re: caller ID and implementer's guide Pete, Just a note about the security matter you mention. Some PC based H.323 endpoints allow one, with just a little knowledge, to persuade them to output debugging which includes all elements of decoded RAS/Q.931-H.225.0/H.245 messages. This is clearly "undesirable" when security of information contained in such messages is required! It also might be quite hard for some people to switch off. I don't have a solution to this: I just raise it as an issue.
