can you or someone who knows summarize the strategy used there ?

i tried to look at the diff in that branch but it is huge,
and so is the code itself in chan_sip, so i couldn't really
figure out the bits related to this part.

surely whoever implemented that thing can give us a short
summary on the approach followed ?
