I have a site that when making an outbound call to a cutsomer the business name is not displayed correctly, but another persons name is displayed. The phone number is correct but the name is wrong. I contacted our service provider for our POTS lines and they say their database is correct and that they are not responsible for the name displayed if outside their network. My question is about how caller id works if pulling a name for the database and who is repsonsible for insuring the database is correct? I thought the provider that call is originated from would be repsonsible, not the service provider of the person that is called.

The name is always handled by the carrier; you can't change it. You can change the number only if using a PRI, not POTS lines. This subject has been going around here a lot lately, so try searching the subject to get more information. Here's one of the other posts:
I had someone call within Verizon service area and the names display correctly( same as Verizon was telling me), but when calling to person that has Optium Cable service providing phone service the names do not pop up correctly. Is there a universial database and how can it be checked? Is there some number that can be called to find out what is in the database?
part of the problem is that different carriers use different cnam databases, so thier is no universal database. if this line was recently ported it is possible the number is still in the old database. You can try the original carrier but not sure if they will be much help. It all depends on your carier and how far they are willing to go to correct the problem.
Anthonyh is right. When you make a call, Your number is passed from one office to the next to the next on the Signaling System 7 (SS7) network untill it reaches the office of the line that will answer your call. The request for Your name is passed back untill it finds the first data base with Your number in it. With Number Porting, Your number can be all over the place.
So, trying not to sound ignorant, is this just something we have to live with? It seems that most telecommunications are taxed by the government. Don't they regulate this kind of thing? I mean, think about it...... I call my wife from work and the name shows "O'Mally's Bar", will she ever believe that SS7 or CNAM failed?
Ed..It all depends on your carrier, and if they are willing to go to bat for you. With porting the cnam trouble usually happens in the office the line is native to basically the co the line it ported from. If the cnam info is still built in the original offices equipment it will pick up that cnam info regardless of what the current carrier has programmed. This will only happen on calls from the native switch. This is when you get "I CAN CALL MY OFFIC IN NEW YORK AND IT WORKS FINE, BUT WHEN I CALL MY HOUSE, IT STILL SHOWS THE OLD NAME" The same principle applies to when a line ports and cannot receive calls from it's native area, they go to ring no answer, the original carrier leaves the number in their switch and never sets the porting triggers when another customer from that native switch tries to call the ported number the native switch sends the call to some dead line somewhere instead of dipping for an LRN (LOCAL ROUTING NUMBER) and sending it to the new carriers switch.
The kicker is unless your carrier tries to correct the issue you are SOL because when you call the original company all they say is "Sorry we show you disconnected from us, call your current provider"
with all these mergers we may start to see less and less of this if they start to combine networks, which by the way is starting to happen, it is more economical to use one data base they five so their may be hope for the future
I had this problem in Chicago several years ago. the ILEC appeared to be cacheing names and only doing the lookup every few days. Customer was with a CLEC, CLEC had the name correct in their database, and if we called an ILEC in another region the name lookup happened correctly, but 'locally' it took almost three weeks to 'correct'.
