GENZAPTELCONF

genzaptelconf -- generates dahdi configuration (TDM adaptors)

genzaptelconf [-sRdvzF] [-c <country_code>] [-e <base_exten>]

genzaptelconf [-sRdv] -l -- only list to standard output

genzaptelconf -su -- only unload dahdi modules

genzaptelconf -h -- Help screen

genzaptelconf is a script to detect dahdi devices (currently mostly TDM cards are supported). It generates both /etc/dahdi/system.conf and /etc/asterisk/zapata-channels.conf

PRI and BRI (with ZapBRI) cards are basically identified as well. However the span configiration is a default that I only hope is sane. Looking for feedback

-c country_code

A two-letter country code. Sets the country-code for the zonezone entries in system.conf , The default is the value of lc_country from /etc/default/zaptel and failing that, "us".

-d

Also try to detect modules. Unloads all dahdi modules and loads them one by one. Considers a module useful if it loaded successfully and if loading it has generated at least one zapata channel.

The list of detected modules is written as the value of ZAPTEL_MODS in /etc/default/zaptel

-e base_exten_num

Configure channel i as extension exten_num + i . This is mostly for the caller-id values. Crude, but may be good enough. See also -r

-F

Disable writing FXS extensions in zapata.conf

-l

Only list deceted channels and their signalling. Don’t write configuration files. Note, however that -ld will still rewrite the modules line in /etc/default/zaptel (see -d above).

-M

Update /etc/modules with a list of our modules, thereby triggers their loading via modprobe on the next boot.

This triggers the -d option as well.

-R

Don’t restart asterisk even if it was stopped using -s .

-s

Stop asterisk for the duration of the test. The detection will only work if nobody uses the dahdi channels:

* To allow unloading of modules

* to allow reading configuration files.

This option tells the script to stop asterisk (if it was running) and to try to start it after the end of the test.

-v

Be verbose. lists the detected modules if -d is used. Lists detected channls. In the end tries to connect to asterisk to get a list of configured dahdi channels.

-z

emulate the operation of zapscan.bin: generate /etc/asterisk/zapscan.conf with the results of the scan.

Look at the beginning of the script for a number of variables that can be overriden through the configuraion file. Some variables can also be overriden through the environment. The configuration file is sourced by bash but for compatibility expected to have only ’var=VALUE’ lines and comments or empty lines.

The configuration will first be read from /etc/default/zaptel if it exists, and /etc/sysconfig/zaptel otherwise (But those file names may be overriden, see ZAPTEL_BOOT_DEBIAN and ZAPTEL_BOOT_FEDORA below). Variables set in those files will override the default settings and setting rom the environment.

The following variables may be set from the environment: ZAPCONF_FILE, ZAPATA_FILE, ZAPTEL_BOOT_DEBIAN, ZAPTEL_BOOT_FEDORA, DEVZAP_TIMEOUT, ZTCFG

lc_country

The default country. Can be also overriden by the option -c

base_exten

The base number used for automatic numbering

context_manual

If set to ’yes’, no context changes are made in zapata-channels.conf

context_lines

The context into which calls will go from dahdi trunks.

context_phones

The context into which calls will go from dahdi phones.

context_manual

If set to ’yes’, no group settings are made in zapata-channels.conf

group_lines

The group number for dahdi trunks.

group_phones

The group number for dahdi phones.

ALL_MODULES

modules list. Used for unloading and modules detection. The order of modules is the same for both.

ZAPCONF_FILE

ztcfg’s configuration file. The sane default is /etc/dahdi/system.conf .

ZAPATA_FILE

The generated partial zapata.conf snippet. Default: /etc/asterisk/zapata-channels.conf .

ZAPTEL_BOOT_DEBIAN

The Debian Dahdi defaults file. Normally /etc/default/zaptel

ZAPTEL_BOOT_FEDORA

The Dahdi defaults file on various other distributions. Normally /etc/sysconfig/zaptel .

DEVZAP_TIMEOUT

Maximal number of seconds to wait for /dev/zap to be initializaed by udev.

ZTCFG

The full path to the ztcfg tool. Default: /sbin/ztcfg genzaptelconf will also explicitly test for /usr/sbin/ztcfg as a last resort.

/etc/dahdi/system.conf

The configuration file used by ztcfg to configure dahdi devices. re-written by genzaptelconf . A backup copy is saved to /etc/dahdi/system.conf.bak .

/etc/asterisk/zapata.conf

The configuration file of Asterisk’s chan_zap. Not modified directly by genzaptelconf. If you want genzaptelconf’s setting to take effect, add the following line at the end of zapata.conf:

#include "zapata-channels.conf"

/etc/asterisk/zapata-channels.conf

This is the snippet of chan_zap configuration file that genzaptelconf generates. . A backup copy is saved to /etc/asterisk/zapata-channels.conf.bak .

/etc/default/zaptel

This file holds configuration for both genzaptelconf and /etc/init.d/dahdi . It is sourced by both scripts and can thus be used to override settings of variables from those scripts.

/etc/modules

A debian-specific list of kernel modules to be loaded by modprobe at boot time. When the option -d (detect) is used, genzaptelconf will write in this file dahdi modules to be loaded. If you want to use a different file, set MOD_FILELIST . If it is rewritten, a backup copy is saved to /etc/modules.bak .

The backup copy of /etc/modules

ztcfg(8) asterisk(8).

If you override a configuration variable both through the environment and through the configuration file, the value from the configuration file wins.
