vboxgetty: isdn voice box (getty)
SYNOPSISvboxgetty [OPTION] [OPTION] [...]
DESCRIPTIONVboxgetty is the heart of vbox: it watches the isdn system and waits for incoming voice calls,
- -f, --file FILE
Config file to use. Default is the file '/etc/isdn/vboxgetty.conf'.
- -d, --device TTY
ISDNdevice to use. You must use this option!
- -h, --help
Show summary of options.
- -v, --version
Show version of program.
CONFIGURING VBOXvboxgetty should be started from the init process. To do this you need one line per vboxgetty in /etc/inittab like this one:
I5:2345:respawn:/usr/sbin/vboxgetty -d /dev/ttyI5
The next step is to set up a working configuration for all ports in /etc/isdn/vboxgetty.conf: read vboxgetty.conf(5) how to do this and look at the example config file in /usr/doc/isdnutils/examples.
You should then create the spool directories for each user: /var/spool/vbox/<user>, /var/spool/vbox/<user>/incoming and /var/spool/vbox/<user>/messages. Copy the example config files vbox.conf and standard.tcl from /usr/doc/isdnutils/examples to /var/spool/vbox/<user>, read the man pages vbox.conf(5) and vboxtcl(5) and edit these config files.
Change the owner of all files in /var/spool/vbox/<user> with "chown <user>.<group> /var/spool/vbox/<user> -Rv" and correct the permissions with "chmod o-rwx,g-rwx /var/spool/vbox/<user> -Rv".
The last step: run "init q" to force init to reread /etc/inittab
HOW IT WORKSFor each line in /etc/inittab one vboxgetty is started by init. Make sure the first field (ID) and the device file are different. Each vboxgetty does this:
First /etc/isdn/vbox.conf is read, the global settings are loaded and then the port specific settings. Then vboxgetty waits for an incoming call.
On an incoming call vboxgetty reads /var/spool/vbox/<user>/vbox.conf (unless you change that name), and vboxgetty determines if it should take that call or how many RINGs it should wait. It also gets the name of the standard message, beep message, timeout message, if these should be played and an alias for the current caller, if there is one.
If vbox has waited enough RINGs and the caller is still ringing, it takes the call and starts the tcl script /var/spool/vbox/<user>/standard.tcl (unless you change that name), and this script will do the rest (normally: play standard and beep message, record and then play timeout message).
