There may/may not be an immediate need to tweak/change things to make DTLS related processing (hopefully just on the local stack level rather than on on-the-wire protocol- with some supporting SIP enhancements) more “failover friendly”. This issue requires more analysis/discussion but does not sound unsolvable IMHO.
We will have to solve client connection reuse for both TLS and DTLS sessions though. Unless you want to have
client certificates on all devices.

Adam as chair: SIP Client Connection Reuse is something we’ve disussed under multiple names - “half outbound” or “why is ;transport=tls”
deprecated” or “Why doesn’t SIP Outbound happen?”. Maybe that deserves a milestone.

For example, I would like to see some input on WHY to do it, and HOW it is intended to be deployed etc. How does DTLS fit SIP? What are the advantages? OR, do we want to specify DTLS-for-SIP simply because DTLS is “hot”?

Based on recent discussions on the mailing list, the following topics have some mind-share behind them. What I'd like from everyone with an interest in any of these topics is to indicate (a) whether you are willing to actively review and comment on documents on the topic; and (b) what priority each task has relative to each other: there are five topics; please indicate a unique priority from one (most important) to five (least important) for each topic.
