Customer has a DSU II 16x32 with a Whozz Calling Lite 8 (manf. in 99). I set the customer up 8 years ago with AT&T as their carrier (6 POTS lines). Everything worked. CID on phones, etc.

Moved them to new location with another provider (Charter Cable). Same hookup, but no CID info displayed on phones.
Checked programming, etc, etc looks good.
Plugged computer into Whozz Calling box make test calls and nothing.
Change baud rates, zippo.
Change from Comdial to Whozz Calling format and I get "No CallerID" output AFTER I hang up the line (not during or after the CID burst).

I dont have another CID to test with, so I bring the unit to the office (where I've got an AT&T POTS line) and it outputs about 60-70% of all calls (cellphones give it trouble).

Contacted CallerID. Great people. I was told that the problem might be the phone providers used to adhere strictly to the Belcore 202 / Telecordia format. The unit I have isn't upgradeable and thus SOL...

Has anyone ever heard of this or had issues with this? I've got people talking to me about CID-08's, but I'm a little worried they'd have the same issues.

Anyone?

Buy yourself a cheapo cid phone or cid box and retest your lines! I'll wager your box is working fine but its got nothing to work with.

Sorry that I didn't include that - but hooking up a CID box works. Putting the buttset to the line, I can hear the burst between the 1st and 2nd ring.

makes you long for the days of bell. It is the carrier not the box. However good luck trying to fined anyone at the cable company that knows what the bell standard is. DO a search on caller id here and see alot of info on this.

Ok - I think its fixed.

I wish I had some step-by-step to tell you what I did, but it came down to making my 2nd - 3rd call with charters support. I was bumped up to someone who put me on hold while they checked things out. Ding Ding "magically" it started working. Never talked to that tech again. As soon as I was off hold, I was transferred to another .new. tech and I asked what the other tech did - they didnt know. Nothing is in my ticket.

At this point. I dont know. I dont care. It works.

My first post was more along 2 points - 1. Has anyone ran into CID hardware not working (esp the old Comdial CID stuff) because of format issues and 2. it felt like CallerID was wanting me to purchase a new one (hard sell).

In the end, it really doesn't matter now.

Glad you got it fixed!

What I've seen a number of times is they send the CID information too soon after the first ring cycle. Specs say the window is 500 to 1500 ms. Chances are they adjusted the timing.
