VoIPo outgoing CNAM

[stevech]

Does the link to the Level-3 DIScussion relate to the outgoing CNAM topic of this thread?

Sorry. I thought is was clear that outbound CNAM has mostly to do with the carrier VOIPo uses to register your name. That is how it propagates through the LIDB servers. (Is your number on Level3, or another provider that VOIPo used?)

When you call someone, their phone company looks up a LIDB server to get the name that matches the number. That is also how VOIPo gets the names on your incoming calls.

Nobody sends CNAM for outgoing calls. It is the receiving carrier's responsibility to use LIDB.

Looks like this http://forums.voipo.com/showthread.php?t=2108 is a parallel thread on CNAM.

VoicePulse claims to be able to do it (at least my reading of http://www.dslreports.com/forum/r250...ble-on-request). Not sure how much of this is "marketing" but on the face of it, it appears to be a nice feature.

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?
