Re: LCR1.14-MISDNV2-Asterisk11-No DialTone?

Hi Gianni,

I cannot recollect LCR/Asterisk/mISDN/mISDNuser/Kernel versions of my
productive HorstBox.

But these days I played around with new software versions on my test
HorstBox. Seems to work; dialtone, calls both incoming and outgoing,
etc. Though not yet extensively tested.

Below is a more detailed description.

Cheers,
Arnold



Hardware, Software
------------------
HardWare: Telephony board "Horst" in Horstbox Professional.
   CPU: XScale-IXP42x, i.e. ARM 32 bit
   ISDN Cologne Chips bri HFC-PCI
     1 x wired for nt mode
     1 x wired for te mode (unused by me)

General Software Environment:
   OpenWrt trunk from https://dev.openwrt.org/wiki/GetSource
   git clone of revision 4934a03cda29a140e6d82fbb0c3e22fe71d7153f
   Linux: 3.10.49 as selected by OpenWrt

More OpenWrt prepared software from "OpenWrt telephony feed":

   git clone of revision fe4b4a6db7904f35bcaf3373b9458b9c64e11a88
   Asterisk 11.13.0 as selected by OpenWrt telephony feed.
   Some patches applied to Asterisk by Openwrt;
   most probable not related to ISDN.

mISDN drivers:
   OpenWrt package built by me
   from git://git.misdn.eu/mISDN.git
   git clone of revision b77c4645bc5acb0a2640a209197fe654606cdf2f
   (newer revision did not build with kernel 3.10.49)

mISDNuser user space software:
   OpenWrt package built by me
   from git://git.misdn.eu/mISDNuser.git
   git clone of revision ed6c40581e344e6baa948c9aee1c33cb33682f5b

LCR:
   OpenWrt package built by me
   from git://git.misdn.eu/lcr.git
   git clone of revision ea45edac0622fe96ae967bdd048cec7d03c11210


Specifics
---------
- Both the hfcpci driver in linux kernel and the external provided
   (mISDN) hfcpci driver worked only after being patched as described
   here:
     http://permalink.gmane.org/gmane.linux.isdn.i4l.user/6297
- The mISDN_core module which comes with the linux kernel 3.10.49 did
   not work, the external provided module (mISDN) works.
- The mISDN_dsp module is required by LCR. Both the module from the
   kernel and the module from the external mISDN software are fine.
- The echo canceller module mISDN_dsp_oslec comes with the external
   mISDN driver software only.
