Member-led peering cooperative

A neutral peering network for communications providers.

SIP Federation helps participating providers keep eligible traffic between members, under shared technical rules and member-led governance.

This is not a cheap-minutes or general PSTN termination business. Membership does not promise legal exemption — each provider remains responsible for its own customers and obligations.

Three reasons to join

One interconnect, shared rules, and a say in what comes next.

01

Connect once

A shared federation interconnect instead of one-off bilateral relationships. One authenticated connection reaches every member that has agreed to receive traffic through the federation.

02

Peer with confidence

Known member identity, shared operating rules, and a controlled media boundary. You know which provider is on the other side of a session and what rules they have agreed to.

03

Build what comes next

Help create an open communications identity layer that can grow beyond phone numbers — governed by the members who depend on it.

In plain English

What the federation actually does

When a participating provider has a call for a number served by another participating provider, the federation can identify the serving member and deliver the call through the federation instead of an ordinary wholesale path. Calls that are not eligible remain on the provider’s normal route.

Members register the customer destinations they serve and agree to receive through the federation. They do not publish termination routes, and the federation is not an anonymous termination vendor — it is a shared peering and policy boundary.

Where this is going

SIP is the starting point, not the ceiling.

Phone numbers remain useful public addresses and are not going away. The longer-term ambition is that portable, verified identities can become an additional, interoperable address type — specified in the open and governed by members rather than by a single vendor.

The practical network

A working multi-provider peering exchange with an eligibility directory, member policy enforcement, controlled media, and usage records. This is what the founding-member pilot builds.

The standards movement

An open conversation about portable identity, attributable routing claims, and interoperability commitments that outlive any one operator.

Founding-member announcements and charter progress

  • Founding-member applications open

    We are recruiting a limited group of providers to shape the operating rules and run the first multi-provider interconnect.

  • Draft charter published for comment

    The proposed governance structure is open for founding-member input before anything is ratified.

Updates are edited directly in index.html and founding-members.html.
