Also, as a side note, I wouldn't suppose there's any alarm lines wired on these CO's are there? Sometimes, an alarm system will pick up calls too. Sometimes they're coded if a call ring no answers after so many rings then then alarm will pick up the next call and answer with it's weird, warbaly modem tone.

Good luck on the meet. You would do well to bring a single line (analog) phone with built in caller ID and use that off the line without the Samsung connected.

That will prove crapbeyond is the problem.

I thought it was ShightBeyond

i have had a few customers with simular problem,although it had nothing to do with caller ID,if the call was answered at a certain point during the ring cycle the user would hear an odd type of ring(kind of like when you monitor a ringing line with butt set).the call would drop then would ring back the system again.Outside caller would only hear normal ringing.I could pretty much time it when calling with my cell and answering it while i started to hear 2nd ring as the outside caller.
I spoke to tech support and they advised me to replace the 4TRK card with a NEW 4trk card.this fixed the trouble.It has happened on 3 or 4 sites.the telco provider in each case was not the traditional Bell/ATT telco but rather a Cable Company/telephone provider.Samsung said it had something to do with a change in ring voltage the Cable company was providing during the offhook answering state.

Update. Cbeyond changed out their IAD and it fixed the problem.

Thanks for the help everyone.

Thanks for the update Chazrc
