Hi Max, I'm currently working on some redesign of my ISDN4BSD stack in cooperation with the FreeSwitch project. One of things that I want to do is to have all ISDN adapters appear like network devices. The ISDN protocols usually use something called Q.921 which is similar to TCP, only very simplified. The Q.931 part will either be in userland or in the kernel, and is used to do the telephony signalling like SETUP, CONNECT and RELEASE_COMPLETE. The idea is that once you use a socket you can easily change the layer2 to TCP, SCTP, UDP or whatever to be able to run Q.931 accross ethernet. --HPS Current I4B homepage: http://www.selasky.org/hans_petter/isdn4bsd _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
