[cisco-voip] Calling Party Name Question

[Keith Klevenski]

Reviving an old thread...

 

I ended up getting the telco to set the CNAME for outbound calls out our
MGCP controlled PRIs for a certain range of DIDs to reflect the name of
the customer just fine a few months ago.  We were running CCM 3.3.5 at
the time.  Since then we upgraded to 4.1.3 and it seems (although I
cannot confirm 100%) that after the upgrade suddenly the CNAME on
outbound calls from this customer's range of numbers now says our CNAME
again.  

 

Can anyone confirm whether a CCM upgrade from 3.3.5 to 4.1.3 could cause
the CNAME for a certain range of numbers not to work anymore?  The
number is presented fine, but the CNAME is now back to our company name
rather than our customer's name which we had the telco change a few
months back.  I can't find anything obvious on the gateway configuration
page and it would seem that the telco would be in control of this as
long as we are sending the calling number.

 

Thanks!

Keith

Actually, this is a great question.  

 

Calling Name or CNAME is very similar to DNS in that it is a distributed
database out in the SS7 network that contains numbers to "owner" name
mappings.  This database costs carriers money to subscribe to and there
are various levels of subscription.  That's why some smaller carrier
don't have CNAME at all or maybe only a subset of names lookups.  So,
your question gets to this:  Whomever assigned you guys the numbers,
that you in turn have assigned to your customers, entered your companies
name in the CNAME database as the owners of those numbers.  In order to
change the delivered CNAME globally, you need to have that entity update
the database with the correct companies ownership of those digits.

Hi all,

 

I know this is going to be a total n3wb question, but here goes...

 

The Calling Party Name is provided by the telco and I'm assuming there
is no way to change this internally on specific calling numbers for
outbound calls that leave our PRIs.  We provide managed/hosted telephony
services for a couple of our customers' small offices and they reported
that a couple of calls they made to others showed our company name
instead of theirs.  This would be expected of course, but I just wanted
to confirm that there is no way to change that on our end (CCM 3.3 soon
to be 4.1.3, MGCP), but is strictly on the telco side.  I'm assuming
this is the case and I'm also assuming the telco isn't going to put a
different CPN on outbound calls from specific calling numbers.

 

Are my assumptions correct?  

 

TIA!!
