Germany NGN Interconnection...but where is IMS?

Interconnecting VoIP networks I thought was the job of IMS and related peering setup (IPX?).
Now it seems that XConnect is doing it in a partnership. And the XConnect I know has emerged from Internet VoIP technologies, connecting the Internet VoIP islands.
Definitely an interesting case to be followed. If we see more of these, it will change the world.


From the story:
The DE-CIX NGN service resolves these challenges by offering national and international network operators a secure hub for NGN interconnection, with benefits including:

• Multilateral NGN interconnection to multiple networks, by-passing the PSTN, and reducing the need to create and manage numerous commercially and technically onerous bilateral IP interconnects
• Improved Voice quality and support for higher-value multimedia services
• Number portability corrected routing via a Centralised Number Portability database (CDB) to ensure accurate call routing
• Policy control to define and manage the technical terms of each interconnection and support for different settlement models between operators
• Reduction of capital and operating expenses, transit charges, and resource requirements for creating and managing interconnects, from interoperability testing to implementation
