[dispatch] Introducing ViPR: a new federation technology

[Jonathan Rosenberg <[e-mail]>]

Folks,

As you are all well aware, SIP has been very successful in the 
marketplace as a tool for voice and video within a single domain. Its 
success for inter-domain federation has been more limited, and it has 
seen almost no deployment over the public Internet for any-to-any 
federation, even though this was the model originally envisaged for SIP, 
and a model I still believe in.

This is something that needed to be fixed, and I have fixed it.

Today, Cullen and I submitted documents describing a new technology 
called ViPR. ViPR is a new federation technique which will finally 
enable the any-to-any SIP federation that we have always wanted for SIP. 
It solves several hard problems that have prevented widespread 
federation. In particular, it solves the phone number routing problem, 
providing a non-centralized technique that securely maps phone numbers 
to domains. It also provides a built-in solution for the VoIP anti-spam 
problem - a new one that is specific to VoIP. As such, it enables 
worldwide, scalable, any-to-any federation over the public Internet, 
securely, for phone numbers, and in a way that supports incremental 
deployability.

This technology is not just documents - it is working code, and was 
announced by Cisco today as part of their products shipping early next year.

I'm extremely excited about ViPR, and I think others will be too.

The documents are:
