Hi All, I'm using PrivacyGuard to filter calls from withheld numbers. A few percent of incoming calls from my BT landline where I know the caller does not withhold their number. BT deny that they're not passing CLI from all calls. In /var/log/asterisk/messages, the following three lines preceed every such call so far: [Jul 11 11:52:28] NOTICE[23198] chan_dahdi.c: Got event 18 (Ring Begin)... [Jul 11 11:52:29] NOTICE[23198] chan_dahdi.c: Got event 2 (Ring/Answered)... [Jul 11 11:52:31] NOTICE[23198] chan_dahdi.c: Got event 18 (Ring Begin)... These lines do not appear when CLI is passed correctly. I have no idea how to interpret this, or whether it indicates where the problem might lie. Any ideas? TIA, -- Geoff
