Hi!

Has anyone considered the issues covered in the happy-eyeballs draft for SIP?

A 19 or 32 second time out when placing a call is not a good user experience... I think this applies to SIP over TCP, and possibly also needs to be handled for UDP.
I don't see this handled in the draft for IPv6 transition in the Session Initiation Protocol (soon-to-be RFC 6157)

Seems like the scope of the happy eyeballs draft is HTTP, so the question is if this should be expanded or if we need other drafts for other protocols.

Regards,
/Olle
