===Q38,bug: FXO can not call out!===
The problem is this:
1) I cannot make outbound calls on an FXO card (Using FXSKS signalling)until I've received an incoming call
2) resetting the hookstate to offhook(A single ring is good enough),
or alternatively, disconnecting and reconnecting the telephone line.

===Q60, Why are you unable to call out with Asterisk 1.4.22? ===
If you are using wctdm or opvxa1200 with Zaptel and Asterisk 1.4.22 then there is a known issue with outbound calls. The reason you are not able to call out is because Asterisk 1.4.22 has a new feature which detects if a analog line is plugged in or not, but this feature only works with Dahdi. So to fix the issue you can do one of the following.
edit the file under /asterisk-1.4.22、channels/chan_dahdi.c" find this line
#ifdef DAHDI_CHECK_HOOKSTATE return 0;
#else return 1;
Change the "0" to a "1"
#ifdef DAHDI_CHECK_HOOKSTATE return 1;
#else return 1;
Q61, Sound quality issue with wctdm and opvxa1200
you can try these possible solutions:
1) Check the IRQ, make sure system handle IRQ properly
2) Use zttest to check the result
3) Disable the X window and framebuffer(set vga=normal from grub)
4) When using IDE driver, please open the DMA control
5) Bind the card IRQ to particular CPU, for example:
echo 1 > /proc/irq/217/smp_affinity #wcfxo
6) Set the latency timer: setpci -v -s 04:06.0 LATENCY_TIMER=f8 #wcfxo
Q62, Echotraining and OSLEC
if you use the OSLEC, you must disable the echotraining.
otherwise, the channel will be silent.
===Q63, Far side disconnected with disconnect supervisions===
possible solutions:
1) Your PSTN provider uses voltage/battery drop for disconnect supervision,
pleas try to edit DCT in zaptel.h to 100 ms or higher.
2) If you PSTN provider provides reverse polarity/battery
disconnect supervision:
hanguponpolarityswitch=yes
answeruponpolarityswitch=yes
3) If your PSTN provider has disconnect/busy tone disconnect supervision
busydetect=yes
busycount=6
or try to callprogress, and set your progzone to your country code in zapata.conf
===Q64, Cabling for wctdm and opvxa1200===
wctdm/opvxa1200 uses RJ11 cable. please refer this:
===Q65, Splitter for A1200P/A800P===
===Q66, Power supply for for wctdm and opvxa1200===
If you use FXS with wctdm/opvxa1200, you MUST use
12v power supply(4 pin Molex power cable) for FXS, please refer this:
