Any chance of a ground start vs loop start issue? Some PBXs were ground start. Not sure how that would affect caller ID. Is the PBX actually detecting the ringing?

But still does not work on the Lucent PBX. The customer still swears it worked with his old AT&T lines, but seems resigned to the fact that he won't have caller ID Anymore. I tried to sell him into a new PBX, but he "Has a truckload of spare parts for this PBX" On 11/9/2017 3:53 PM, Adam Moffett wrote: Oh right....I haven't picked up the phone yet so there's nothing to hear.

Unless you are listening on a butt set in line or watching the info pass through a switch you wouldn't see or hear it. The only reason I remembered between first and second is sitting at a class 5 switch trying to figure out why caller ID was failing on a feature group D trunk group and seeing them come through after one ringy dingy.

Or maybe it's audible, but so short you don't notice it? I'm fuzzy on this. I probably shouldn't ask. I don't need to know that much about POTS anymore. ------ Original Message ------ From: "Lewis Bergman" <[email protected]> To: [email protected] Sent: 11/9/2017 4:40:57 PM Subject: Re: [AFMUG] ATA CallerID question More info than anyone probably wants to know. I found this about the original question: Caller-ID Signaling According to Telcordia specifications, CND signaling starts as early as 300 mS after the first ring burst and ends at least 475 mS before the second ring burst From here: http://www.tech-faq.com/caller-id.html On Tue, Nov 7, 2017 at 9:29 PM Adam Moffett <[email protected]> wrote: I did not know that tone contained modulated data.
