I installed my first asterisk server 3 weeks ago and everthing went fairly smooth. I got meetme working as well as voice mail and an IAX trunk.
Now I am trying to install two more on nearly identical hardware…
The linux install goes normal (openSuse 10.2). I download the latest zaptel-1.4.3, libpri-1.4.0, asterisk1.4.5, asterisk-addons-1.4.1… I compile and install them in the listed order. I do not get any errors durring the compile of any of the above modules.
I then copy the Asterisk configuration files from the working test server and that is where things stop working well. When I call into the new server I get these loud distortins every 5 to 10 seconds. If I call into a meetme confernce room it prompts for your name (You hear the distortions approx every 5 - 8 seconds). The DTMF is ignored so you can’t enter the confernce. Below is the console output…

The problems continue beyond that. With the new server I can’t check voice mail as DTMF is being ignored there as well.
I run the zaptel speed test and timing test and the results look just like the ones on the working server.
When I reboot the server the Zaptel driver fails (I see a red Fail durring the boot process) and I get the following errors (dmesg)when I try to modprobe for zaptel or ztdummy
zaptel: Unknown symbol crc_ccitt_table
ztdummy: Unknown symbol zt_receive
ztdummy: Unknown symbol zt_transmit
ztdummy: Unknown symbol zt_unregister
ztdummy: Unknown symbol zt_register
If I modprobe for crc_ccitt and then modprobe zaptel and ztdummy respectively they then go active. and the above errors go away.
Our one testing/dev system is running very well but these other two just won’t work right. I have tried 3 diffent linux builds and got the same problem. With each. I move the hard drive from the working unit to the new servers and the build works on the hardware. It appears that this is a build issue. I followd the same build instructions on all three boxes.
