Somewhat, but it has been at the low end of my priorities for a while (work that absolutely has to be done RIGHT NOW overshadows work that should be done and would eliminate the other work on a longer timescale...) > Would implementing it be difficult for someone not used to ISDN > driver internals? Are you used to working in kernel space? You basically need to modify the raw channel interface to allow passing of which number to call (by means of an ioctl()), make that communicate throughout the driver, get mpd with synchronous support from me (unless you want to run the MP branch of iij-ppp), and modify the code to use your ioctl(). > Is there any other way to link both B-channels? Would that way be > compatible with other OSs (eg. Linux?) Yes and yes, respectively. You could get by with just having two connections, and then using multi-directional routing. A patch to allow this form of routing was posted to -hackers a few weeks ago (without any comment about it's relevance or not to ISDN). Eivind.
