Can't get callerid from PSTN

你好，
我使用Elastix 2.0.3，目前在台灣，據我所知，台灣的callerid為 ETSI-FSK 及 DTMF兩種。
我安裝了OPENVOX A400P，並且下載了貴公司網站上的 DAHDI_2.3.0_to_2.3.0.1_callerid_patch.tar.gz，也下載
dahdi-2.3.0.1-3.src.rpm 重新編譯，
我不喜歡每次重新單獨安裝 dahdi-2.3.0.1xxxxx.tar.gz，所以，利用修改 srpm裡面的 spec，產生新的rpm安裝檔案，並且強制安裝。
我修改 dahdi.spec，產生了三個RPMs

dahdi-2.3.0.1-3.i386.rpm
dahdi-devel-2.3.0.1-3.i386.rpm
kernel-module-dahdi-2.3.0.1-3_2.6.18_194.3.1.el5.i386.rpm

用 rpm -ivh *.rpm --force

重新安裝了這三個rpm

並且 dahdi_channels 設定如下
;;; line="1 WCTDM/4/0 FXSKS (In use)"
signalling=fxs_ks
callerid=asreceived
usecallerid=yes
cidsignalling=bell (按照貴公司建議的設定值，我也測試過 v23)
cidstart=polarity (按照貴公司建議的設定值，我也測試過 ring)
hidecallerid=no
group=0
context=from-test (我用來顯示callerid的測試context)
channel => 1
callerid=
group=
context=default

我的 extensions.conf 如下
[from-test]
exten => s,1,Wait(3)
exten => s,n,NoOp(${CALLERID(number)})
exten => s,n,NoOp(${CALLERID(name)})
exten => s,n,Wait(5)
exten => s,n,NoOp(${CALLERID(number)})
exten => s,n,NoOp(${CALLERID(name)})
exten => s,n,Hangup

我的 system.conf 如下
fxsks=1
echocanceller=mg2,1 (聽說oslec會影響，所以改為mg2)
# Global data
loadzone = tw
defaultzone = tw


測試撥入，得到的結果如下
-- Starting simple switch on 'DAHDI/1-1'
-- Executing [s@from-test:1] Wait("DAHDI/1-1", "3") in new stack
-- Executing [s@from-test:2] NoOp("DAHDI/1-1", "") in new stack
-- Executing [s@from-test:3] NoOp("DAHDI/1-1", "") in new stack
-- Executing [s@from-test:4] Wait("DAHDI/1-1", "5") in new stack
-- Executing [s@from-test:5] NoOp("DAHDI/1-1", "") in new stack
-- Executing [s@from-test:6] NoOp("DAHDI/1-1", "") in new stack
-- Executing [s@from-test:7] Hangup("DAHDI/1-1", "") in new stack


這樣測試了半天，發現那個patch好像沒甚麼用處。
請問，該怎樣調整？

附上 dahdi_monitor 1 -r rx.pcm -t tx.pcm 所錄製下來的 rx.pcm + tx.pcm

Hi,
from the record, your cidsignalling is dtmf, pls try this:
cidsignalling=dtmf
cidstart=ring
And pls load the driver like this:
modprobe wctdm cidbeforering=1 opermode=TAIWAN
then try again!
If still not work, pls send SSH to me, i will help you.

Where to load this driver with "modprobe wctdm cidbeforering=1 opermode=TAIWAN"?
Just add "wctdm cidbeforering=1 opermode=TAIWAN" after /etc/modprobe.conf ?
