RE: [Sip] Question about Poll: Proposal relating to keepalive, TCP, and UDP usage in draft-ietf-sip-outbound

[<Erkki.Koivusalo at nokia.com>]

Sorry, I was not clear enough for my formulation.
The scope of my summary was the usage of SIP together

>May support UDP for Outbound

as a rewording of the original proposal:

> Proposal 2: Make outbound registrations over UDP flows optional for
> UAs.
