Conference bridgefail


#1

hi,
I already install the Asterisk v1.2.1 this morning running on CentOS4.2 Kernel2.6.9-22.0.1.EL , and seems like everythings goes ok but I had encounter the message like
"“make: warning: Clock skew detected. Your build may
be incomplete.”"
I cant do any conference bridge function, someone can invise on this.
– Executing MeetMe(“IAX2/301-9”, “6000|i”) in new

the above are the errors shown on the CLI.

did you also install zaptel 1.2.1 and build/install it? Does the module load ok, or if you are using a config script (install it with make config), does service zaptel start return any errors?
if zaptel is working right (make sure of this befoer you start asterisk), you lsmod should show the modules zaptel and at least one technology module (ztdummy or if you have zap hardware, wcfxs, wctdm, etc). /dev/zap/ should exist and there should be a few other devices in it, like /dev/zap/ctl. If you have things like /dev/zapctl then you need to fix your udev file, see readme.udev in the zaptel source.


#3

I am using Zaptelv1.2.1 as well to others
I did check on my /dev/zap and it stated the
[root@CetOS4 zap]# pwd
/dev/zap
[root@CetOS4 zap]# ls
1 2 3 4 channel ctl pseudo timer

and even use lsmod it show
zaptel 206724 8 ztdummy,wcusb,wctdm,wcfxo,wcte11xp,wct1xxp,wct4xxp,tor2

It show some error messages while I am make install
make[2]: warning: Clock skew detected. Your build may be incomplete.
make[1]: warning: Clock skew detected. Your build may be incomplete.
make[1]: Leaving directory `/usr/src/kernels/2.6.9-22.0.1.EL-i686’
