RE: [Sipping] Details on SBC

Hi Samir, also take a look at http://snom.com/download/natf_211.pdf.
There is some explanations of what we are going. At least.

We did ICE ("local media path optimization") in the beginning, but
because of the latest changes in the draft we decided not to do any more
changes until this is in a stable state. We don't like moving targets.
And practically it does not seem to play the role that we thought it
would do. Today I would say it is more important to locate the nearest
SBC for the UA (for a globally operating ITSP).

	Subject: [Sipping] Details on SBC

	Hi:

	We are looking for some details on SBC and how they work in
terms of call flows etc. Any pointers?

	Also, does someone know of an actual implementation of ICE for
NAT/FW traversal. It could be either commercial or open-source.
Something that we could test for performance. Any help would be
appreciated.
