Sorry for the scratchy recording, it was done over three-way to a voicemail. Do you think AT&T is adding new long distance tandems to the network? There's a list of 4ESS tandems that's available on the internet, the last one ever installed was 146T. My guess is this is probably some Sonus contraption, it doesn't fit the same profile as their 5E tandems and newer Genband gear such as the CS1500 and CS2000 are pretty much the same software-wise as DMSes. MG9000 maybe?

This is interesting since the last 4ESS was installed in Atlanta, GA in July 1999 with the Network Switch ID of 146-T. As far as I know this is still in service.

For a number of years, AT&T has implemented a series of what I call "edge switches" in the network using 5ESS switches with the format of NPA-xL where the x is either 8 or 9. (I don't know the significance of either)

But this new switch is interesting. I'd like to see how it could be reached via the AT&T network.

Agreeing with ThoughtPhreaker on this one - it's most likely a Genband packet switch. Older end offices (especially the remaining 1AESS switches) are being slowly converted to MG-9000 switches or remotes. It wouldn't surprised me that they're using a Class 4 grade of softswitch here.

Curious if there are any others out there like this.
