VoIPo outgoing CNAM

[stevech]

Sorry. I thought is was clear that outbound CNAM has mostly to do with the carrier VOIPo uses to register your name.

This posting is because VoIPo suggested that I pay to get a new/better number so that VoIPo's contracted carrier would support CNAM. I did so. But still, I get "cellular caller" as the CNAM for outgoing calls to frequently used numbers.

The impetus for this thread was VoIPo saying

We do not send caller ID name information. It is queried from the database for the underlying number partner. It should say the rate center. It may be cached at the recipient's end where it shows "Cellular Caller" in the name field.

What's not said here is if VoIPo is responsible for publishing name/number to these external databases. And sustain it. Maybe VoIP providers cannot?

All this crud aside, the WAF score suffers for the flaw.


Perhaps this means that VoIPo publishes the name/number pairing and they hope it gets distributed and they hope that the carriers that VoIPo do CNAM lookup (which cost a penny or so), then forward that on in the routing.

Why does AT&T and Sprint long lines most always get CNAM right in POTS and VoIPo et al seem to rarely do so? Is it the penny that the carrier-partners don't want to spend? Is it a technical reason?
