asterisk users - Jul 2009 - Caller ID (name) - where does it come from?

Hi Folks, having an issue with outbound calls through a VOIP provider. Calls
get sent out with the CallerID(number), but where does callerID(name) come
from? Apparently not from provider, as we are seeing different (sometime
missing) names on inbound calls, different than what we have configured.
Apparently this comes from some telco database somewhere? Numbers were
ported from a wired-telco.

It is in a database or CNAM dip.

You just need to contact your provider and tell them to have it
changed.  What you send is moot on the PSTN.

Also call 911 and make sure they have the correct address and
information on file.  I do it all the time for liability reasons, just
make sure you tell them right off that bat that there is no emergency
and you want to verify what they have in their database is correct.

I have never had a problem doing this and try to do it in front of the
big boss to show them it is correct and that I am thorough and looking
out for them.

The Caller ID name, "CNAM" is a separate database owned and maintained
"cooperatively" by the bell operating companies.

Your ITSP is not doing these CNAM lookups for you because they would have to 
pay the BOC's for the 'dips' into the CNAM database.  CNAM is a
little cash
cow that the BOC's are quick to protect.  As such CNAM dips may not be 
cached or re-sold as a term service that you must agree to with your CNAM 
provider.

As far as solving your CNAM problem, you would need to either choose an ITSP 
that will provide you with CNAM data on a per-call basis, OR you need to do 
CNAM dips yourself as I (and many others) do.  Beware that some ITSP's 
provide "best-effort" name data culled from various sources.  It's
not
always terrible but it's not 'coke' it's more like 'dollar
store' cola. :-)

As a call comes in to your dial plan you can populate the CALLERID(name) 
channel variable using the CURL function in your dialplan as so:
exten => 
s,n,Set(CALLERID(name)=${CURL(http://cnam1.edicentral.net/getcnam?q=C&f=S&dn=${CALLERID(num)})})

AND let's not forget the completely separate issue with getting your 
ITSP-provisioned number ENTERED INTO the CNAM database in the first place, 
so people see "Karl Fife" rather than the "city, state" or
worse, some
string of arcane LATA information.  There's a solution to this problem too 
but I digress...

I've posted my personal notes below from about 18 months ago when I was 
searchign for CNAM providers:

-Karl

CNAM  PROVIDRES:

Metrostat.com
about 1.5? per dip,
$30 minimum deposit, refundable
CNAM service not well documented on web site
A registerd CLEC

Got Name - Out of business?
1.5? per dip. no minimums, no setup

ClearReach Networks
.67? per dip $200 monthly minimum, resell ok, significant setup fees

411xml.com
more expensive than ClearReach.

p.s.
Once you've got a reliable CNAM source, you can save a few bucks per month
on all of your POTS lines & PRI spans by opting out of the carrier-provided
CNAM.
IIRC, We save something like $40 per month per span on our PRI's & $3
per month per line by opting out of CNAM.  When a call comes in we populate it
ourselves using a quick HTTP GET.

CALLERID(name) is a TELCO specific field.  In the long run, you will be best
served using your own lookup of a database using CALLERID(num), since
CID(name) is unreliable and in some cases costly.  IMO, you would be well
served with an app (AGI?) that recorded valid names into the database and
let you insert the names where they aren't.
