[VoIP] Asterisk on Wyse Diskless 941G "Thin" client terminal

Sat Sep 22 09:35:07 CDT 2007

The dual-Ethernet interface, with separate MAC
addresses, was waiting when I got back from a business
trip to Ottawa. I dropped it into the one and only PCI
slot in the Wyse box and set up /etc/zaptel.conf to
use each of the interfaces as a T1 over Ethernet
setup, with SF 2600 supervision. This involves putting
two entries in zaptel.conf, something like this:

#
# Zaptel Configuration File
#
# This file is parsed by the Zaptel Configurator,
ztcfg
#
#
loadzone = us
defaultzone=us

dynamic=eth,eth1/00:14:66:70:E8:E7,24,0
dynamic=eth,eth2/00:13:46:E6:F7:78,24,0

sf=1-24:2600,10,inverted,2600,0,inverted
sf=25-48:2600,10,inverted,2600,0,inverted

To create the trunk groups, each entry references the
MAC address of the OPPOSITE interface. I then connect
the two RJ45 connectors with a crossover cable. I'm
using the Zaptel ZTDUMMY module for timing. As soon as
Zaptel and Asterisk start, the NIC lights on each
interface flash continuously. I now have a tandem
trunk that, with the proper patches, allows MF didgit
addressing.

The Wyse unit seems quite stable. I've switched my
exchange over to it full-time. I still have a
duplicate backup partition on my other computer for
emergency use. The Wyse is on a UPS that keeps my DSL
modem/router, the Wyse switch, and activity printer
running for 1+ hours on a power failure. The system
also recovers itself if power should fail completely,
as I have the BIOS set to auto-boot on restored power.
Asterisk is running as a daemon, with additional
startup scripts to bring up the ethernet interfaces
correctly.

Now, I need to add a process to refresh my DynDNS
entry when my dynamic IP changes. I've been running
the refresh software on one of the kids' machines, but
have been caught a few times when the Windows machine
has been shut down and the ip address changed!
