chan_dahdi.so not building on asterisk-1.6.2.6

Asterisk Asterisk Support
1

Hi,
I am trying to install asterisk-1.6.2.6 and configure a Wildcard TDM800P.
Linux is RHEL 5
After installing libpri and dahdi-linux, dahdi-tools (using yum) and restarting. I built asterisk, and it is running fine.

But I see that it has not build chan_dahdi.so.

ls /usr/lib/asterisk/modules/chan_dahdi.so

ls: /usr/lib/asterisk/modules/chan_dahdi.so: No such file or directory

Asterisk CLI
localhost*CLI> load chan_dahdi.so
No such command ‘load chan_dahdi.so’ (type ‘core show help load chan_dahdi.so’ for other possible commands)

I see that the drivers are installed fine …
Below are the details of my installation …

rpm -qa | grep libpri

libpri-1.4.10.2-1_centos5

rpm -qa | grep dahdi

kmod-dahdi-linux-fwload-vpmadt032-2.3.0-1_centos5.2.6.18_164.15.1.el5
dahdi-firmware-2.0.2-1_centos5
dahdi-firmware-hx8-2.06-1_centos5
dahdi-firmware-tc400m-MR6.12-1_centos5

dahdi-linux-2.3.0-1_centos5
kmod-dahdi-linux-2.3.0-1_centos5.2.6.18_164.15.1.el5

AND

lsmod | grep dahdi

dahdi_echocan_mg2 10248 0
dahdi_transcode 12164 1 wctc4xxp
dahdi_voicebus 45120 2 wctdm24xxp,wcte12xp

crc_ccitt 6337 2 wctdm24xxp,dahdi

I have run the make samples on asterisk whivch creates the chan_dahdi.conf default.
and I have the default /etc/dahdi/system.conf with channels as follows

dahdi_cfg -vv

DAHDI Tools Version - 2.3.0

DAHDI Version: 2.3.0
Echo Canceller(s): MG2
Configuration

Channel map:

Channel 01: FXO Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 01)
Channel 02: FXO Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 02)
Channel 05: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 05)
Channel 06: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 06)

4 channels to configure.

Setting echocan for channel 1 to mg2
Setting echocan for channel 2 to mg2
Setting echocan for channel 5 to mg2
Setting echocan for channel 6 to mg2

thanks

hi:
you can manually copy the file to modules.

thanks James… that worked for me.

now the next problm seems to be a config issue. I’ve installed all dahdi drivers and no zaptel. (with yum)

when i run the asterisk, the log gives me this error
^[[1;30;40m == ^[[0;37;40mParsing ‘/etc/asterisk/zapata.conf’: Found

now since i’l loaded all dahdi drivers, and also set the dahdichanname = yes in asterisk.conf, is it not supposed to look for /dev/dahdi/channel ?

[root@localhost dev]# ls /dev/dahdi/
1 2 3 4 5 6 7 8 channel ctl pseudo timer transcode

I tried renaming the folder dahdi with zap, but that fails something else, also tried making a soft link ln -s dahdi zap

or am i missing something ?
asterisk itself is otherwise up and running.

thanks

hi:
check this:

40mdahdi_open^[[0;37;40m: Unable to open ‘/dev/zap/channel’: No such file or directory

i think there are some softlinks wrong or please change this:
/etc/asterisk/asterisk.conf file:
dahdichanname = no

thanks for the reply james. I have currently fallen back on asterisk 1.2 as I had to bring up an asterisk system on priority.
I will get back to this again once I’m done with my req.

thanks a lot for the time …
