I think you'll find the CID signal is being sent outside of the normal window of 500 to 1500ms after the first ring. A CID box doesn't care but a number of phone systems do.

You might ask them to check. I'll guarantee you if you hooked up a POTS line from Bell the CID will work correctly. I've dealt with this exact same issue dozens of times with multiple phone systems (especially Tecom and older Vodavi). The most annoying part is when I show the CLEC that their caller ID isn't working but is on the Bell line, they deny having a problem. To them if a cheapo CID box works then they're good to go. Even using a Viking CID generator to prove to them the KSU is good doesn't sway them.

Here's a post from a couple of years ago when I first started dealing with these CLEC CID issues. Things haven't improved much since then. :bang:

Very interesting link, Bill. I'm convinced it'll help us in the future...thanks.

And since it's fios there's a very real possiblity that's exactly the problem. Do the ground thing first it will be easier if that's the problem.

No wonder you look so old for 30 Bill.

Before I forget, ask them to reprogram the channels as G.711 and see what happens. I'm not quite sure just exactly where the CID is generated using VOIP circuits but I've seen units programmed as G.728 or G.729 where CID doesn't work reliably.

took single line phone to d-marc comming into building and caller id works on all lines. i did notice that when i hooked the xblue the caller id showed that the call came in but did not display the name or #. it registered the info but did not display it, only on ver2 of the ksu. custoner said that line 1/2 are fiber and line 3 was copper. any suggestions?

What have you found with the previous suggestions?

The data treatment can be critical and CID is a data signal. As a comparison, Vodai requires G.711 if a fax is to be used with their RSGM. .

Well xblue system will not work on this fios network. Itried 2 new xblue ksu and no luck. tried an atlas system and worked fine. i also tryed to get verizon to reprogram for g.711 but the tesh had no clue what i was talking about. So I will install an ivx c clas system. thanks for your input

Once again reaffirming my opinion of Verizon. :bang:

It is a "known problem" with the X16, confirmed this with x-blue a couple of years ago. I thought they had licked that problem though.

Maybe you have an older KSU???

Call Ernie Meadows from X-blue to see if they can advance you a newer KSU.

I believe that the problem exists on Verizon lines based on the Central Office equipment used in your area. In other words, it may work with Verizon at certain Central Offices.
The predominant carrier where I am is Cablevision, so I have not seen this problem recently.

Bottom line is if you hook up a caller id unit and all works, it is an x-blue problem, not a carrier problem.
