How to fix Dahdi-Wanpipe Drivers in ScopTEL
If you have updated your ScopTEL PBX server to use a
new CentOS kernel, it can sometimes happen
that DAHDI/WANPIPE drivers need to be recompiled
To verify if dahdi is properly compiled and working:
From ssh do: timertest
You should see a test result, if not then dahdi is not properly compiled. In this result timertest is functional.
[root@sip ~]# timertest
Set timer duration to 8000 samples (1000 ms)
Timer Expired (999 ms)!
Timer Expired (1998 ms)!
Timer Expired (2999 ms)!
Timer Expired (4000 ms)!
You can also check if dahdi is compiled on the active kernel with 'dkms status' and 'uname -a'.
dkms status will print the installation status on all installed kernels.
uname -a will print the active kernel version.
[root@sip ~]# dkms status
dahdi, 2.11.1-11.el7.scopserv, 3.10.0-1127.el7.x86_64, x86_64: installed
wanpipe, 7.0.26-1.el7.scopserv, 3.10.0-1127.el7.x86_64, x86_64: installed
[root@sip ~]# uname -a
Linux hostname 3.10.0-1127.el7.x86_64 #1 SMP Tue Mar 31 23:36:51 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
If you've been getting issues with Digital/Analog interfaces and drivers
refuse to start, here's how to fix it.
To fix the problem, we’ll need to remove current installed drivers. So open
an SSH connection to the server and execute the following
service asterisk stop
service dahdi stop
rpm -e dahdi wanpipe dkms-dahdi dkms-wanpipe
Now that drivers are cleaned, you must reinstall drivers, this step will
always download the latest version available on ScopServ RPM
You must execute this command from SSH to reinstall packages:
scopserv_yum install dkms-dahdi dkms-wanpipe -y
Finally, from the ScopTEL GUI, you must Commit
configuration on the Telephony module.
Then it is recommended in SSH to do:
service dahdi start
service asterisk start
As you can see, the procedure for reinstalling the DAHDI
and Wanpipe drivers on your ScopTEL PBX is
