Yeah that's exactly what I was talking

Beautiful
One
workaround (kludge/hack) I've seen is to store the last successful SDP somewhere, then
intercept and drop the 488 and replay the last offer/answer with the stored SDPs.
(Absolutely not something I would consider a proper solution…)
That will break more
than it helps.
But is there a way to “revert” back. Let’s say I store the last successful SDPs - can I
transmit them to RTPengine to revert. If I have the dialog module I could very well save
them within the context of the dialog. Would be nice
to have a “rtpengine_revert()” command that resets back to the state before the last
INVITE, the last successful state with complete offer and answer.
That's what a theoretical handling of 488 etc would entail, yes…
