× Questions about B100/200/400/800 ISDN BRI Cards

Asterisk 1.6, B200P and D410P configuration

10 years 2 days ago #5684 by casey0999
Hello all-

I am configuring a system with Asterisk 1.6 and these two Openvox cards for BRI and PRI. In the past I have used bristuff and libpri with older versions of Asterisk, but now I would like to upgrade to Asterisk 1.6. Question, should I be using mISDN or libpri for these cards when they are in the same system, or does DAHDI now support both cards under asterisk 1.6 ?

DAHDI supports both cards, BRI cards using wcb4xxp driver, PRI cards using wct4xxp driver.
(See this thread: )

BUT we suggest you use mISDN instead of DAHDI with BRI cards, because mISDN works greatly with BRI cards.

and DAHDI supports PRI cards with no problem.

OK, I will take your advice and give this combo a try.

I'm running Fedora 12..

Help please!
My configuration is: Fedora 12 (kernel is 2.6.32), IBM System x3650 M2
I am trying to install Asterisk 1.6 and DAHDI

I don't think I can use mISDN v1.x because it won't compile with this kernel.
I don't think I can use mISDN v2.x because OpenVox hasn't provided patches for it(?)

I would not like to use bristuff, because it only goes to Asterisk 1.2 and 1.4, not 1.6

So i thought I would try the latest DAHDI, which supports the Digium BRI board, but
I think I need OpenVox patches to make it work with the OpenVox B200P.

DAHDI can detect the OpenVox board, but not configure it:

lspci finds the B200P, and reports it as an ISDN board with Cologne chip set [HFC-4S] (rev 01)

dahdi_hardware command returns the following:
"driver should be 'wcb4xxp' but is actually 'hfcmulti' <- NOTE THIS MESSAGE
pci:0000:16:02.0 wcb4xxp+ 1397:08b4 OpenVox B200P"

dahdi_cfg and dahdi_scan do not see the OpenVox board.

Is there a patch to be applied to the DAHDI drivers to have them use the OpenVox board?

If you use daidh with B200P, you need to add some patches.You can refer this link:
I suggest that you should use Centos+misdn.

Hi- Yes, reading those patches now, but it appears that by now (18 months later) I think they would be already incorporated into the latest DAHDI? I may be loading the modules in the wrong order, or may have to set some configuration parameters manually, I will try this and report back.

Using Centos is not an option (my customer is a Fedora Core shop), and mISDN seems much less desirable given the comments that I continue to see. (however, it's a fall back if necessary and I'm willing to go back to an older kernel)
