[Sipping] new draft on ICE for opening SIP dialogs: draft-lowekamp-sipping-ice-for-sip-00

Title:             Using ICE to establish SIP Dialogs

Abstract:
This draft explores a way SIP can be extended to allow a new dialog
directly between the endpoints to replace an initial dialog that had
one or more proxies in the signalling path.  This technique relies on
ICE to perform hole punching that allows a direct connection to be
used in deployments where a sip-outbound proxy or SBC is used to
establish SIP connections across NAT or firewall boundaries.  It can
also be used to replace such a dialog with a secure connection
directly between the endpoints.  This technique can be applied to
traditional proxy-based SIP routing as well as to emerging P2PSIP
deployments that lack centrally located proxies.

This draft describes early work that evolved from ideas initially
developed for P2PSIP that are no longer being pursued.  We are
interested in feedback on whether there is broader interest in these
techniques.
