OpenVox A1200P/A800P + Dahdi

hello, all of users:
we releases a1200p/a800p to support Dahdi. To install a1200p/a800p with dahdi, install some support packages as zaptel requires, then please go through these steps:
1) get dahdi-linux, dahdi-tools and asterisk
wget downloads.digium.com/pub/asterisk/releas...erisk-1.6.0.1.tar.gz
wget downloads.digium.com/pub/telephony/dahdi...i-linux-2.0.0.tar.gz
wget downloads.digium.com/pub/telephony/dahdi...i-tools-2.0.0.tar.gz
please unzip and cpoy those files to /usr/src/dahdi/dahdi-com(please note that this my dir, you can set to /usr/src)

2) cd /usr/src/dahdi/dahdi-com/dahdi-linux-2.0.0/drivers/dahdi
open Kbuild file and add the one line like this:
=====================================
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCT4XXP) += wct4xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTC4XXP) += wctc4xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM24XXP) += wctdm24xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTE12XP) += wcte12xp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += wctdm.o
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += opvxa1200.o
// this is for a1200/a800p
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCT1XXP) += wct1xxp.o
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTE11XP) += wcte11xp.o
==========================================
after edit the file, please download the opvxa1200.c to the directory.
3) please change back to /usr/src/dahdi/dahdi-com/dahdi-linux-2.0.0
run: make, make install
4) change the directory to /usr/src/dahdi/dahdi-com/dahdi-tools-2.0.0
run: make, make install
5) change to asterisk directory, in my case is /usr/src/dahdi/asterisk-1.6
5.1) ./configure
5.2) make
5.3) make install
5.4) make samples
6) please edit the dahdi files
6.1) edit the system.conf under /etc/dahdi, some files are there:
[root@new-host-8 asterisk-1.6]# cd /etc/dahdi/
[root@new-host-8 dahdi]# ls
init.conf modules system.conf
please keep in mind that the system.conf works as zaptel.conf in zaptel
the part of system.conf will be like this:
# And change channel 2 to use the kb1 echo canceller.
#echocanceller=kb1,2
#
fxsks=1
fxsks=2
fxoks=3-12
6.2) edit the chan.dahdi.conf in /etc/asterisk
the part of chan_dahdi.conf should be like this:
;stripmsd=1
;callerid=asreceived
group=0
signalling=fxs_ks
context=demo
channel => 1
channel => 2
signalling=fxo_ks
context=from-internal
channel => 3-12
the chan_dahdi.conf works as zapata.conf, so do not be confused.
6.3) edit extensions.conf
for incoming line: // for example only
================
[demo]
;
; We start with what to do when a call first comes in.
;
exten => s,1,Wait(1) ; Wait a second, just for fun
exten => s,n,Answer ; Answer the line
exten => s,n,Dial(dahdi/12) // zap has been changed to dahdi
exten => s,n,Hangup
==================
for internal:
===================
[from-internal]
exten => 1,1,Dial(dahdi/8|60|m(default)) // zap has been changed to daidi
exten => 1,2,hangup
exten => 2,1,Dial(dahdi/3|60|m(default)) // zap has been changed to dahdi
exten => 2,n,Hangup
======================
7) modprobe dahdi
modprobe opvxa1200
9) dahdi_cfg -vvvvvvv // note: ztcfg changes dahdi_cfg. more commands are under /usr/sbin
============result of dahdi_cfg=========
[root@new-host-8 ~]# dahdi_cfg -vvvvvvvv

James, did you ment that we shouldn't use file from previous post or from some other thread ? I mean, will the version from 1st post in this thread work with DAHDI 2.0 or I should wait for new file ?

hello:
you can try this new version. please keep in mind that, if you just want to try or play for the new system, it is ok. otherwise, please use the 1.4.21 and zatepl, or other previous zaptel because the dahdi is not a stable version at movement. anyway, if you have any problem related with a1200p/a800p, please let me know. the first thread of this topic is a very brief intro to install A1200P/A800P, you can follow that and please make sure the version of asterisk is correct.
regards!
