可能你的舊電腦零件中有這張soft modem card，部份可以在asterisk 使用，但有部份兼容出現問題。
你可參考這網頁

One of the most affordable ways to test Asterisk is to use a X100P card. This card is actually an old V.90 modem. Some manufacturers still sell the card even after Digium had discontinued it. Recently, we were having a lot of problems in new motherboards. The symptom was very easy to detect, when trying to run the utility dahdi_test the result was simply0%. Another common issue was the message below:
[Jun 24 09:52:23] ERROR[3064] asterisk.c: Asterisk has detected a problem with your DAHDI configuration and will shutdown for your protection. You have options: 1. You only have to compile DAHDI support into Asterisk if you need it. One option is to recompile without DAHDI support. 2. You only have to load DAHDI drivers if you want to take advantage of DAHDI services. One option is to unload DAHDI modules if you don't need them 3. If you need Zaptel services, you must correctly configure DAHDI.
Diagnosis:
The problem is easily diagnosed using the utility dmesg.
[ 7.600941] FXO PCI Master abort
[ 7.620308] NOTICE-wcfxo: WCFXO/0: Unknown DAA chip revision: REVB=0
[ 7.620311] Failed to initailize DAA, giving up...
[ 7.620343] wcfxo: probe of 0000:03:00.0 failed with error -5
After a lot of reasearch I found the solution in trhe bugtraq.
Check https://issues.asterisk.org/view.php?id=14232
The problem is apparently caused by the initializing process and now power saving methods.
Solution:
To solve the problem, please download the patch https://issues.asterisk.org/file ... =21202&type=bug
Apply the patch to the file wcfxo.c
cd /usr/src/dahdi-linux-2.2.0/drivers/dahdi
patch –p0 wcfxo.diff
make uninstall
make clean
make
make install
I hope this tutorial helps you, I've spent months tracking for this solution. |
