[cisco-voip] Anyone in the US sending Calling Name with Calling number?

Thu Mar 18 17:17:09 EDT 2010

Carlos is correct, just cause you can, doesn't mean they will honour it. 

That's in fact, another difference with US vs Canadian Telcos. In Canada, they mostly want you to send that information, where in the US they do the SS7 lookup. And the look up is arbitrary. Well, not controlled anyways. 

When we first went IP, the last person to register a directory listing with our main number was a hamburger joint. For months, any call from us to the US appeared from this hamburger joint. 

It was not fun.

Allowing you to send Calling Name doesn't really do much for you. From 
what I understand, if the terminating LEC does a lookup on the number 
then the LIDB database name information they retrieve is what will be 
displayed. I have not seen any LECS as of yet that just take what you 
send them and display it. I'm pretty sure a majority of them don't.

Calling number? 

I was unaware that caller-sent CNAM was delivered anywhere in the 
US. The fact that the terminating CO does the CNAM lookup has 
been a convenient way to get reliable reverse-lookup info on any 
given number. 

For example, my home in California is served by an at&t BRI. 
at&t doesn't deliver CNAM at all on BRIs, so when I get an inbound 
call, I simultaneously ring the phones in the house and send the 
call back out to a CID-equipped POTS line via an ITSP. When the 
call comes back into the house via the POTS line and into an FXO 
port, I replace the CID on the ringing phones with the information 
from the POTS CID delivery. So to watch a phone ring in my house, 
you'll see just the number for the first few seconds, then you see 
the number and the name. 

This wouldn't work if CNAM relied on data sent by the call originator. 

Does anyone have an example of a LEC or NPA-NXX-X in the US where 
CNAM is delivered as sent? I'm intrigued.
