We have something in there with a NAT... but I don't think we have a use case that covers the situation where one or both users is behind a NAT or firewall that blocks UDP entirely (which fortunately also covers some of the NAT cases where ICE doesn't succeed). This would require media over TCP... something that I believe some of the implementations have already tackled in different ways, but there's no use case and no drafts proposing which solution to choose either.
