View source for Installing and configuring Zaptel

=Zaptel driver=
To compile the Zaptel driver, we first install support for certain functions (a.o. deflate compression method):
 sudo apt-get install zlib1g-dev libssl-dev bison debhelper
Specifically the last one (''debhelper'') can bring a whole slew of extra packages with it, a.o. ''build-essential'', ''po-debconf'', ''liburi-perl'' and ''patch'', just to name a few.
Next up is to get the zaptel source code, as is delivered with Debian Lenny:
 sudo apt-get install zaptel-source
If there are any dependencies not yet satisfied, you'll see those packages come with the source code (e.g. ''module-assistant'').

Once the zaptel source code is on our system, it is up to us to create the driver. Debian can't handle this for us, as the zaptel driver has to precisely match both our hardware platform and the linux kernel we're using. So we're going to compile our own driver - yippee!<br>
Debian has placed the source file package in /usr/src, and it's named ''zaptel.tar.bz2''. Unpack it with ''sudo tar xjvf''; this creates a subdirectory structure /usr/src/modules/zaptel, which then blossoms in four directories. The zaptel directory holds a.o. a script named ''configure''; if we run it, it does a LOT of checking (if we have a suitable compiler, if the system has ''grep'', if we have the right kernel header files etcetera). It should end with the following lines:
 configure: creating ./config.status
 config.status: creating build_tools/menuselect-deps
 config.status: creating makeopts
 config.status: creating build_tools/make_firmware_object
 configure: *** Zaptel build successfully configured ***
This means we can now do the actual building: 


=Zaptel tools=

Next up, we need to install the ''zaptel'' driver and userland tools (v1.4.11 under Debian 5.0), which will in turn require ''fxload'' and ''libtonezone1''. Installation is simply performed by
 sudo apt-get install zaptel fxload libtonezone1
After installation, the ''zaptel'' driver checks for the existance of ''/etc/zaptel.conf''. When you've never before had Zaptel on your system, you probably get the message
 zaptel : /etc/zaptel.conf fails test for exists and readable
This is in fact a friendly reminder that you first have to create this file, before you try to load the driver.

=Zaptel configuration=
The Zaptel driver is configured by means of its ''zaptel.conf'' configuration file. The contents of this file are fairly straightforward:
