Hi, I am joining this thread late, but, would anyone out there be interested in exchanging traffic with other carriers directly over SIP? The service would just look like a carrier, except it would know how to reach all other participants directly with SIP, bypassing TDM land, and enabling rich media as a fringe benefit, as media would be direct between endpoints. I have a proof of concept and am wondering who out there might be willing to do some testing. Email me directly if interested, to talk about your network and how something like this might fit in.

If you already have SS7 services via Sigtran then going into a Frontier area would just be a matter of adding another SS7 for that tandem.

*nods* We take SIGTRAN over IPSec over the public Internet, then convert to SS7 over DS1s in some old Ciscos.

We use them at $DAYJOB. We've had no issues with syniverse themselves in the recent years while I've been at the company. But plenty of issues with the transport providers to reach them. Luckily never both at the same time. Including a number of instances of flapping. Note, these are A-Links over TDM, not SIGTRAN at this time.

Anyone in here using Syniverse for these services and can speak to their reliability?

There are pros and cons to everything. It sounds like in your case you may just want to keep your ISUP trunks and SS7 links, but maybe look at another provider for SS7. Syniverse is also an option but I'm not sure if their service has gone downhill like TNS' apparently has.

Right, but as I said earlier, I'm already in the same building as the tandem, so I'm just adding points of failure for moving an existing operation somewhere else.

When you use a PSTN connection provider you route your traffic to them
via SIP and they handle all the SS7 so you can eliminate your direct LIS trunks with the LEC and your SS7 Links.

Well right, but wouldn't I still need all of the same stuff (perhaps a few less trunks to specific switches, only now I have fewer minutes to spread the costs over?

Even without IPES you can switch your feature group D to voip through these aggregators and get rid of basically everything that isn't the local LEC's legacy network.

Sure, but then I just transfer the problem to someone else, until the traditional PSTN goes away or modernizes. I am working on IPES for expansion markets, though.
Also, for my home LATA, I'm needing to be in the same building as the primary tandem, so it's kind of a selling point for large customers in that area that I would have fewer opportunities for failures. I don't have to go to Chicago and back to get to the operator in the next row of racks over. Though, I suppose my SS7 diversity and availability is the weakness, not the actual call path.

Reduce your reliance on it more and more. Switch to IP tandems (Inteliquent/Peerless/etc) and ip interconnect. The people who make and support SS7 equipment are in a dying market, the brain drain on it is immense as people retire, and the longer you rely on it, the worse it's gonna get.
TNS is a big dog in the space. But that's not saying much anymore.
