Yeah that's exactly what I was talking about. You can replay the last
successful rtpengine_offer()/_answer() with a stored SDP, and that would
revert the call to the last state. That's what read_sdp_pv and
write_sdp_pv config params are for.
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...
