Try reinstalling zaptel first, and look for any errors in the output.<br />

<div>
Basically do as the previous poster suggested.<br />
Have you installed a newer operating system kernel?<br />
If you do then you should reinstall zaptel as it compiles kernel modules for that specific kernel version.

So basically, you had a version conflict between zaptel and asterisk.<br />
<br />
I had a similar issue, after upgrading Asterisk to 1.4.22,...I had to change zaptel to 1.4.9.2..... and it was fixed instantly.

Hi everybody,<br />
I am having a very particular problem with my TC400B transcoder card.<br />
I cannot load TC400B card. I am using zaptel-1.4.12.1, asterisk-1.4.24 versions on RHEL4.4. <br />
When i run modprobe wctc4xxp command, the following error occurred below.<br />
FATAL: Error inserting wctc4xxp (/lib/modules/2.6.9-42.ELs<wbr />mp/extra/w<wbr />ctc4xxp.ko<wbr />): Unknown symbol in module, or unknown parameter (see dmesg)<br />
then run dmesg command:<br />
wctc4xxp: Unknown symbol setup_timer. <br />
<br />
Have never had this problem before on asterisk-1.2.x, zaptel-1.2.x version and same OS.<br />
<br />
Any advice, please?<br />
<br />
Thanks,<br />

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.
