Subject: [sipcore] Keep forward strategy

Hi,

I intend to submit a new version of the keep draft soon.

My intention is to move back to the Via parameter based solution, based on comments I've received.

That means that the negotiation will be between adjacent nodes (either during initial dialog request, or when the route set has been established).

My intention is also to remove the non-dialog/registration related "ping" use-case, as it seems like OPTIONS would be a better candidate for that. That means that keep-alives negotiated during the registration phase will be sent during the lifetime of the registration, and keep-alives negotiated during a dialog establishement will be sent during the lifetime of the dialog.

Some other mechanism will then be used for "pings", which lifetime are not related to any registration or dialog.

Regards,

Christer
