Good Day!

I installed a single server setup on the other site, when i test it to call by logging in the agent I got this error

WARNING[13552]: app_meetme.c:1259 build_conf: Unable to open DAHDI pseudo device

and it hung up and the next error is this

WARNING[13610]: app_meetme.c:4840 admin_exec: Conference number '8600051' not found!

DAHDI Version: 2.10.0 Echo Canceller:

Also did you install on a physical server or on a virtual machine??

What leads you to believe dahdi is not installed?

output from:
Code: Select all
lsmod | grep dahdi

your BEST bet at this stage is to do a full reinstall and SKIP the "zypper refresh / zypper up" stage. often there are package irregularities that break dahdi, but the versions that install directly from the CD are valid. So use the ones on the CD and you'll probably have no problem. Just be sure you whitelist lockdown your server so the general public can't attempt to hack your system.

Thank you William, yes is truth to skip #zypper up -r before vicibox-install.
Is not the best way to make zypper up -r before install the vicibox. The best way is to install phase 1 #os-install and config #yast lan, after #yast timezone, and in the end the #vicibox-install


Now I have install all and dahdi.

But for config the LOAD BALANCE it wil be done by manual config? Because some times when I add the second server, extensions-vicidial.config It will update automatic with new server and with load balance...

WHy happen this WIlliam?

The BEST way to cluster/multi-server is by doing so during the installation with Kumba's Vicibox .iso (Standard, never express). His method of clustering is unquestionably the best method and fully automated. Any slight adjustments you may want to make after the fact are "configuration preferences" by you, not "clustering problems".

If that does not resolve the question: Note that this thread is related to DAHDI Psuedo Device, you should create a new thread with more details related specifically to what you are talking about.
