[VoiceOps] AT&T / Onvoy / Vonage call routing screwup after LNP

Sounds like a possible ENUM routing issue if it's bypassing the PSTN. Was Vonage notified of the port away by Onvoy?

Had similar experiences, but with different vendor.
I would try to open a ticket with ATT to fix their routing. I know, it won't be easy.
I would also try to speak with Vonage. I wouldn't have the customer disconnect before calls are flowing correctly.
If this doesn't work, and you wait another day or two with no results, I may try to port the numbers away from convoy.
Interested to know how you solved it...

So here's a weird one: we took over a small business account from Vonage. Vonage was using Onvoy for origination, and we elected to keep the TNs with Onvoy (through a wholesaler). So the "port" only consisted of Onvoy repointing traffic for those TNs internally away from Vonage and to our reseller, with no LRN change.
The weird bit is that we definitely are seeing some traffic for those numbers hitting us, but it's been nearly 72 hours now and some calls are still ringing their Vonage ATAs. I couldn't tell you definitively where the delineation is, but I can tell you, for example, that if I call any of the TNs from my AT&T cell, those calls still hit Vonage, so I can at least reproduce the problem at-will. This is for a local real-estate office, and AT&T is big in our relatively rural market, so even if it turns out that AT&T is the only provider that is affected, that is still a huge percentage of our end-user's client base. And the frustrating bit is that traffic is now effectively being "forked", which is a huge inconvenience for our end-user since they have an old key system with analog trunks and so we have to choose between having our IAD hooked up to their KSU or having their stack of Vonage ATAs hooked up. (For now, we have left the Vonage ATAs in place, and we are forwarding calls tha
t come to us to a single line from the ILEC that this office ended up keeping. I don't know what we would have done if they didn't have that line.)
Onvoy swears up and down that everything is configured correctly on their side, and given that we are at least getting *some* calls, I am inclined to believe them. When I give them call examples from my cell phone, they say that they don't even see those calls hitting their systems at all. At this point, the running theory is that AT&T must have some kind of direct peering with Vonage, and Onvoy isn't in the loop at all on those calls. If that's the case, then perhaps everything magically works itself out once I have the end-user call up Vonage and have them close out the account completely. But I'm not sure it is worth the risk of having them take that step with things as they are, on the off-chance that I guessed wrong (instead of the problem getting fixed, calls from AT&T start going to /dev/null).
Has anybody encountered anything like this before, or heard of national wireless carriers doing direct peering with national VoIP providers while completely bypassing PSTN switching infrastructure? Are there any AT&T, Onvoy, and/or Vonage reps reading this who can help un-**** this cluster?
