Have you read the documents I've been refering to many times? The
"future" architecture for pineapple (www.codename-pineapple.org), the
current one that I wrote up after the kill-the-user disaster (caused
by me, myself and propably I).
Those two combined are a good starting point for writing up a new one.
Easy to find if we had svn view... ;-) Search the list and you'll find
plenty of pointers. I'm a bit off-line now and can't find them. Maybe
Writing this up will take some time, that I currently don't have
plenty of and no funding for. That's why I keep pushing you guys to
start doing it with the starting points I've given you earlier...
Maybe we can set up a discussion on IRC on this topic or schedule a
Regardless, until someone has stepped forward with an architecture
that we all can approve, I want to put this patch and my patch on hold.
What it's really time to do, is to fork chan_sip and start from
scratch with this model *without* a requirement for backwards
compatibility. Keep the old junk and create a new channel that will
have a realtime system that people understand and that works, a
configuration set that people understand and that works and
documentation that people understand... But where on earth will we get
the time and resources for that?
Not having that time, and not having the required documentation is not
a good excuse for integrating patches that have a high risk of
breaking more than they are solving.
Long rant from a jetlagged mind in a cold country called Sweden :-)
