What is an IPES?

IPES stands for “IP Enabled Services” — but honestly, nobody calls it that in conversation. In practice, an IPES is a VoIP provider that has been authorized by the FCC to get telephone numbers directly from the national numbering administrators, just like the big phone companies do.

Before the FCC opened this door, VoIP companies had to get their phone numbers through an underlying carrier — usually a CLEC or an ILEC. That meant extra cost, extra complexity, and a middleman standing between you and your numbers. The IPES framework changed that by letting qualifying VoIP providers go straight to the source.

What makes an IPES special?

The big deal is 50-state authorization from the FCC. If you’re a CLEC, you have to get certified in every single state where you want to operate. That’s a lot of paperwork, a lot of lawyers, and a lot of waiting. An IPES gets a single federal authorization that covers the entire country. One filing, nationwide reach.

That’s a huge — dare we say enor-moose — advantage if you’re building a VoIP company and want to serve customers everywhere without spending years collecting state certifications.

So what’s the catch?

There are a few trade-offs, and they’re worth understanding before you go down this path.

No direct interconnection. An IPES can’t plug directly into the public switched telephone network (PSTN) the way a CLEC can. You’ll need an intermediate carrier to bridge that gap. This adds a layer of dependency — and cost — to your operation.

No intercarrier compensation. When a call terminates on a CLEC’s network, the originating carrier pays the CLEC for that termination. It’s a small per-minute fee, but it adds up. An IPES doesn’t get that revenue. Calls come in, but you don’t get paid for receiving them.

You still have to register in all 50 states. This one surprises people. Yes, the FCC gives you nationwide authorization to get numbers. But most states still require you to register, file for a certificate, or at minimum notify them that you’re operating. The federal authorization doesn’t exempt you from state-level obligations. It’s less burdensome than full CLEC certification in each state, but it’s not nothing.

Is an IPES right for you?

If you’re running a VoIP operation and want direct access to numbering resources without going the full CLEC route, an IPES filing is probably worth exploring. We help companies through the process and can help you weigh the trade-offs. And if you’re already operating as an IPES, take a look at OptiMoose — we built it specifically to manage the operational side of running one.
