Hello, I'm evaluating to possibility to use chan_misdn as a short term workaround, in case latest Dahdi is not stable enough for what we are planning to do (we wish to use Junghanns and Digium BRI hardware with Asterisk 1.6) . I've read www.mISDN.org but still have a couple of questions : 1. Is correct that in a 2.6.27 (and up) enabled kernel, the "embedded" mISDN version is 2.X ? 2. Is it correct that Asterisk MUST use chan-lcr to access this mISDN software or is it still possible to install mISDN 1.X to be able to use chan_misdn ? 3. Am I correctly understanding README in Dahdi-linux when I think you can switch Digium B410P support from dahdi to chan_misdn, just editing /etc/dahdi/modules file ? 4. Would you trust chan_misdn as a valuable short term solution for ISDN BRI with Asterisk 1.6 ? Regards -------------- next part -------------- An HTML attachment was scrubbed...

Oliver, I have some comments, but am looking for a good answer to this as well. 1). 2.6.27 kernels to include a version of mISDN v2.0. It's not as up to date as the full version on the mISDN.org site. 2). From my understanding chan_lcr is the preferred way to connect Asterisk to mISDN v2.0. From what I've read it does require some form of the LCR software to function. It was a whole level of added complexity that I didn't want to add to the AstLinux project (unless we're forced to do so to support mISDN in Asterisk 1.6+). From a project maintainer's point of view, having mISDN functionality in dahdi is a total win, provided that enough European ISDN hardware is supported. A more interesting approach are these new ISDN cards that appear as a network interface to the system (using a Realtek chip I believe). A few of the ISDN users who use AstLinux are starting to look at those cards. What we've decided to do at this point in the AstLinux project is to continue using mISDN v1 with Asterisk 1.4 releases. We have not been successful in building chan_misdn against Asterisk 1.6 (but then again, we haven't tried very hard either since we're hoping for a better solution as mISDN v1 has more than it's share of issues).

Dahdi has been working fine for me for a few months, using a Junghanns DuoBRI and asterisk-1.6. I have used bristuff before, it usually worked fine, but separate patch. I also tried chan_misdn but quickly abandoned.

I have used both misdn and dahdi_bri over the last year, and would happy take dahdi if for no other reason that it's much easier to install. A patch is available to allow dahdi_bri to work with Asterisk 1.4, and I have used that successfully.
