Installation
Common problems with Zaptel and CentOS:
1) Common errors when compiling Zaptel with CentOS 5.2
vi /usr/src/zaptel-xxxx/kernel/xpp/xdefs.h (-xxxx is zaptel’s version)
please edit the file at line 114:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,19)
typedef int bool;
#endif
by:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,19)
#if LINUX_VERSION_CODE != KERNEL_VERSION(2,6,18) || ! defined(hex_asc)
typedef int bool;
#endif
#endif
2) Common errors when compiling Zaptel 1.2.17.1, 1.4.2.1 or 1 with Centos 5
if you want to use centos 5 to compile Zaptel 1.2.17.1, 1.4.2.1 or 1.4.1, you may
meet with the following errors:
/usr/src/zaptel-1.2.17.1/xpp/xbus-core.c: function ‘debugfs_open’:
/usr/src/zaptel-1.2.17.1/xpp/xbus-core.c:171: error: ‘struct inode’
hen in line 164 approximately of xbus_core.c file, we must change
please edit the xbus_core.c at line 164 :
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,19)
by
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,18)
3) Common Error when compiling zaptel
The screen shot shows that you forget to edit ./configure command when you
compile zaptel. Please run the following command one by one:
开源通信 | www.openvox.com.cn

A400P/A400E FAQ
make clean
./configure
4) The LED of A400 is not on after compiled zaptel & asterisk
This is because you haven’t configured /etc/zaptel.conf and
/etc/asterisk/zapata.conf, please go to /usr/src/zaptel-xxxx/kernel/xpp/utils,run
the command:
./genzaptelconf -sdvM
for auto-configuration. If the LED is on after you run the command, it means
your hardware is working fine. Otherwise, please check if you have connected
the system power to your card or run the command :
dmesg
After that, if you see the output same as the underline one below, it looks like
that you really forget to plug in the power cable to the A400P. Please shutdown
your computer and plug the power cable to the card.
-- DID YOU REMEMBER TO PLUG IN THE HD POWER CABLE TO THE A400P??

5) What are the differences between FXS and FXO interfaces?
FXS (Foreign eXchange Station) is an interface which drives a telephone. FXS
interfaces get phones plugged into them, delivery battery, and provide ringing.
FXS interfaces are signalled with FXO signalling.
FXO (Foreign eXchange Office) is an interface that connects to a PSTN line. It
enables your PBX to have the access to the public telephone network. FXO
interfaces use FXS signalling. FXS interfaces allow you to hook telephones to your
PBX, and FXO interfaces allow you to connect your PBX to real PSTN lines.
6) Do I have to install OpenVox card when installing Zaptel? What is Zaptel?
No, you don’t have to. Zaptel is the driver for asterisk hardware. It can detect the
hardware by read the configuration file in etc/zaptel.conf. The zaptel.conf can be
set by hand or automatically set by running the genzaptelconf –sdvM under
/usr/src/zaptel-1.4.11/kernel/xpp/utils/
(The zaptel is supposed to be installed in zaptel-1.4.11)

2) Why my card gets an IRQ miss?
Each piece of hardware takes 1,000 interrupts per second. When, for some
reason the cards get less than this, an IRQ miss occurs. You can see if the card is
missing interrupts using 'zttool.'
IRQ misses can cause different problems with Asterisk. Symptoms of IRQ misses
are bad audio quality or perhaps PRI errors, although IRQ misses will not cause
alarms. Also DTMF detection not working is something that can be caused by
IRQ misses as well.
Several common things that contribute to IRQ misses are:
-Running the X window system
-Shared IRQs
-No hard drive DMA
-Hard drive DMA too high (shoot for udma3)
-Running serial terminals or frame buffers
To check for shared IRQs you can run:
# cat /proc/interrupts

A400P/A400E FAQ
MIS 0
Notice the A100P card sharing with the sound card, and the A400P card is
sharing with the USB controller. This is likely to cause problems at most of the
time. If you are not using any USB devices, then it would probably be fine. But it
would be better to disable USB or get the card on its own IRQ.
There are several ways to move cards to their own IRQ.
-Turn on APIC
-Tweak BIOS settings
-Try a different PCI slot
-Use setpci
3) Connect analog telephone to FXS channel but find no dialing tone
It’s probably because your channels haven’t been configured correctly. Please use
command
“ ztcfg –vvvv”
Check the output , it should like:
It means your configuration in /etc/zaptel.conf have some error,FXS channels use
the FXO signaling,FXO channel use the FXS signaling,so edit zaptel.conf:
fxsks=1
fxsks=2
……
Run command “ztcfg –vvvv” again to check
Then check /etc/asterisk/zapata.conf ,if you use command “./genzaptelconf
–sdvM”, please check /etc/asterisk/zapata-channels.conf, make sure the
channels config is the same as zaptel.conf(FXS channels use the FXO signaling,
FXO channel use the FXS signaling),restart asterisk。

4) How to remove the old asterisk before install a new one?
First, please stop asterisk module and uninstall it.
The red color command will stop asterisk and close all.
killall -9 safe_asterisk
killall -9 asterisk
then please remove zaptel driver and check what modules have loaded:
[root@zebru]# lsmod | grep zaptel
zaptel
214820
2 wcfxo,wctdm
crc_ccitt
2113 1 zaptel
edit command to remove:
modprobe -r wcfxo
modprobe -r wctdm
modprobe -r zaptel
enter “lsmod | grep zaptel” again , the output should be null。
Remove Asterisk:
Run the following command , then you can remove the asterisk
system(Unrecoverable)。Before you do this, please backup the file you wish to
keep. For example, the log file and asterisk’s config。
rm
rm
rm

Voice quality
1) When dialup on the analog telephone, it shows busy tone in CLI
This problem may be caused by the configuration in your extensions.conf,
asterisk doesn’t “recognize” the number you dial, then it reports you busy
tone. The following picture shows us their relationships:

2) SIP softphone can’t be registered the asterisk server
1. Please check if the Linux system’s firewall and SELinux is close. If not, please
close them or it will cause the problem below .
2.cd the sip.conf,check your sip extension to see if the setting is correct .
The follow is a basic configuration :
[202]
type=friend
username=202
secret=111111
host=dynamic
context=internal
3) Why can’t I get any Caller IDs?
In some PSTN connections, you have to subscribe to CALLER ID from the telco. In
other cases, the caller id is delivered between the first and second ring, so start
by waiting a while before answering, i.e. exten => s, 1, wait(2), exten => s, 2,
answer
4) echo problem
Please verify that your rxgain and txgain are set to 0 in your zapata.conf during
testing. High rxgain and txgain settings can cause echo.
Please verify that your echocancelwhenbridged option is set to no. Generally, it
is not necessary, and in fact undesirable, to echo cancel when the circuit path is
entirely TDM. You may need to enable this only under the rare circumstance
that you are unable to completely eliminate echo otherwise.
The echocancel option in the zapata.conf file only enables echo cancellation for
Zap channels. Please try an echocancel setting of 64 and an echotraining
setting of 800 for testing. Valid settings for echocancel are 32, 64, 128, and 256.
Valid settings for echotraining are 10 - 2000. The echocancel and echotraining
options may need to be tweaked in order to fully eliminate echo. This will be a
trial and error test that must be performed in order to determine the best
echocancel and echotraining settings for your system. Start with an echocancel
setting of 32. Start with an echotraining setting of 100. Increment the
echotraining setting by 100. Do not exceed an echotraining setting of 1200.
开源通信 | www.openvox.com.cn
11
A400P/A400E FAQ
Increment the echocancel option to the next highest setting if you still exhibit
echo after reaching an echotraining setting of 1200. Repeat this process until
you find the settings that completely eliminate echo. Asterisk must be
restarted in order for these changes to take effect.
5)
Does the openvox card have echo cancel software?
No, zaptel has the echocancel function. You can also use Octasic SoftEcho
but you will have to buy the licence first。
6)
Common Problems with trixbox CE
zapata-channels.conf hasn’t been included by zapata.conf
Please refer to chapter 2, question 1
7)
Asterisk can’t detect hang-up signal properly
There are several settings in zaptel.conf and zapata.conf that you can experiment
with. If you are using loopstart, try using kewlstart instead. Kewlstart is
loopstart with disconnect supervison. Your telco must have whats called
"disconnect supervision" configured on the line. Another name for disconnect
supervision is "forward disconnect".
You may also edit the ZT_KEWLTIME variable in zaptel.h. Navigate to the
#define ZT_KEWLTIME line and change the value from 500 to 1000 (You'll need
to recompile zaptel before this takes effect).
You can enable busydetect and busycount to detect when a call has been hungup.
Set 'busydetect=yes' and 'busycount=10'. You may experience hangups if your
busycount number is too low, so increase the number until you find a variable
that you're comfortable with. You can also try enabling callprogress, and set
your progzone to your current country code. Callprogress is experimental, so if
you experience frequent disconnects, you should disable it. Busydetect and
callprogress are ways to try and detect a hangup in software which isn't as
reliable as having the actual signalling indicate the hangup.
If you're telcom uses polarity switching to signal for answer and/or disconnects,
you should use 'answeronpolarityswitch=yes' and 'hanguponpolarityswitch=yes'

A400P/A400E FAQ
8)
Why am I getting a clicking noise?
If a clicking noise is present when dialing through an FXO or when getting
dialtone from an FXS, this is caused by echotraining. Turn it off to get rid of the
clicking. The click is necessary for the echotraining.
9) How to solve the hang-up problems in random calls
If you have busydetect=yes or callprogress=yes in zapata.conf then this is why
the problem happens. You might want to try to set busycount=10 if using
busydetect. As a last resort you may just change busydetect to no:
busydetect=no. Then asterisk won't try to detect the hangup on incoming calls.
Notice that if "Loopstart with Remote Disconnection Supervision" (Kewlstart) is
working for you than you don't need busydetect=yes at all. You can know if your
current config is set to Kewlstart if you have a line fxsks=channel_no in
zaptel.conf and signalling=fxs_ks in zapata.conf.
