How to determine the board arrangement when there are more than one AST board?
If zaptel is configured automatically, you may check /etc/zaptel.conf or /etc/dahdi/system.conf to see the board arrangement. If zaptel is configured manually, you may execute the command #cat /var/log/messages | grep "Launching card" to check the board arrangement. If the board arrangement is determined by their serial number, pay attention to the time when you execute the command.
How to install the SynAST driver in a dahdi version for which driver and tools are published separately?
Please download the driver and tools of dahdi separately.
1.By Script
#cd /opt # enter the directory to source codes
#tar –zxvf SynAST-2.0.1.0.tar.gz # decompress the SynAST driver
#cd SynAST-2.0.1.0 # enter the directory to the SynAST driver
#cd dahdi # enter the directory to the ‘synway ast for dahdi’ driver
#./Setup install # install the driver
Would you like to install SynAST AST package now? y # enter ‘y’ to install
Please enter working dahdi directory [q](exit install) : /opt/dahdi_driver
# enter the directory to dahdi_driver source codes
Please enter dahdi_tools source directory [q](exit install):
# enter the directory to dahdi_tools source codes
SELECT TEJ MODE [t, e, j] :e # select the tej mode, or the driver will be installed in e1 mode
SELECT TEJXAPCI [75, 120]ohm # set the impedance of the TEJ pci board, 75 for coaxial cables, 120 for twisted-pair cables
SELECT TEJ201E [75, 120]ohm # set the impedance of the tej201e board, 75 for coaxial cables, 120 for twisted-pair cables
2.Manually
#cd /opt # enter the directory to the package of SynAST source codes #tar –zxvf SynAST-2.0.1.0.tar.gz # decompress the source codes #cp –rf /opt/SynAST-2.0.1.0/dahdi/srcs/fxm/fxm8apci /opt/dahdi_driver/drivers/dahdi # copy the fxm8apci driver to the dahdi_driver directory. #cd /opt/dahdi/linux/drivers/dahdi/fxm8apci # enter the directory to SynAST source codes in dahdi #make # compile the driver #insmod fxm8apci.ko # load the driver #cd /opt/dahdi_tools # enter the directory to dahdi tools #./configure #make # compile dahdi_tools #make install # install dahdi_tools
How to determine the use of Zaptel or Dahdi for Asterisk?
For Asterisk-1.4.21 and versions below, use Zaptel; for Asterisk-1.4.22 and versions above, use Dahdi.
How to solve the problem that the system fails to detect the hangup at remote end as the volume of the recorded busy tone is quite low?
Modify the file main/dsp.c under the Asterisk directory, changing the previous content ‘#define DEFAULT_THRESHOLD 512’ to ‘#define DEFAULT_THRESHOLD 448’. The value can be reduced again if the problem is not solved yet.
How to solve the problem that the zaptel driver fails to be installed in the system of Ubuntu 8.10, kernel 2.6.27-7-server?
Use the dahdi driver.
How to solve the problem that the configuration files zaptel.conf and zapata.conf cannot be found under dahdi?
/etc/dahdi/system.conf under dahdi corresponds to /etc/zaptel.conf under zaptel. The configuration files system.conf and zaptel.conf, although differ in name, are the same in content. /etc/asterisk/chan_dahdi.conf under dahdi corresponds to /etc/asterisk/zapata.conf under zaptel. The configuration files chan_dahdi.conf and zapata.conf, although differ in name, are the same in content.
