Yes, I can see that with a dedicated server with an external IP this
wouldn't be a problem but obviously when the nodes are behind NAT it
becomes a problem.
So what are the possible solutions to this issue?
Obviously I could imagine there is the idea of having supernodes in
the same way that Skype does (nodes not behind nat) and using them
as registrars.
Yes this supernodes idea works well in practice. Your cassandra nodes
must also have SIP registrar and Proxy functions and properly perform
NAT traversal for their clients.

Yes, you can use it to replace a dedicated registrar server, yet the
real problem is not storing the location information, is traversing
the NAT for SIP signaling and media. The distributed location server
is just part of the solution. #goodidea

Hi there,
I was thinking about using Cassandra for SIP location lookups.
Does anybody have any ideas on whether this would be a good/bad
idea? It seems to be good for storing Key/Value pairs (and other
data too like presence) but I wasn't sure as it doesn't seem to be
talked about much on this list.
Any thoughts from the experts?
