Hi,
During the recent week I have been talking to the people at
FreeSwitch.org and
we have agreed to build up a new full featured telephony
stack by merging
ISDN4BSD and OpenZAP. I have called the new branch
OpenZAP.hps in my SVN
repo.
As a consequence of this I have therefore decided that the
ISDN part of my
ISDN4BSD project will only receive bug-fixes from today and
on, and will be
considered a stable branch.
Some words about what OpenZAP.hps will bring. The
fundamental part of the new
telephony stack is the node concept. A node is a part that
can
receive "mbufs" using FreeBSD terms. There will be
created different node
types like echo-cancel, format conversion, tone detection,
DSS1 protocol,
CAPI2.0, ... Nodes are addressed by a 32-bit value.
Everything will be built
around the node concept. This gives us an important
advantage that nodes can
be placed in userland, kernel or even at a remote host. In
other words the
load can be distributed easily.
Multithreading. Unlike many other telephony implementations,
there will not be
one thread for every B-channel or call present. Instead
there will be one
thread for each CPU and possibly one configuration thread
running at a lower
priority.
Compatibility. The new stuff will be backwards compatible
with CAPI2.0 and
possibly also the FreeSwitch API, which means you will still
be able to use
it with Asterisk and Callweaver through
"chan_capi", and FreeSwitch
through "libopenzap".
Planning. I suspect that OpenZAP.hps will be ready for
testing before
Christmas of 2008.
Financial support. Feel free to support the project
economically. If you are
interested in working for the project, and have the right
experience, there
is a chance that something can be arranged so that you will
get some money in
return. Currently I cannot offer any full-time positions.
