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. --HPS References: ISDN4BSD repo: ============== svn --username anonsvn --password anonsvn checkout svn://svn.turbocat.net/i4b/trunk/i4b OpenZAP.hps repo: ================= svn --username anonsvn --password anonsvn checkout svn://svn.turbocat.net/i4b/trunk/openzap.hps
