I brought a teleworker phone — er, excuse me, a Mitel 5220 VoIP set —
home from work a while ago to play with, and to use when I work from
home. Some networking issues here (mostly involving being too lazy to
set up a dhcp server behind the second router) prevented me from
getting it up and going until now, so tonight was my first chance
to try it. I can see now why our VARs are getting excited about this.
I have a extension from work sitting on my desk and all I had to do
to get it was plug in a ethernet cable and a power supply.
This is really one nifty setup. First of all, it’s a box that
everyone and their dog would identify as a phone. It doesn’t need
a computer to be around, it’s not a black box with a headset (although
it supports the same headsets our standard desk phones support). It’s just a desk phone that works like a desk phone.
It’s designed (only) for corporate use, so it’s not
“Internet calling” or anything like that. What it does do
is this: You plug it in somewhere that is Internet-connected and
provides DHCP — even behind a NAT gateway — and it works identically
to the way it would work on your desk at the office, with no interaction
at all to get it started. And the control and data connections between
the phone and the office are encrypted, so you don’t need to establish a
VPN from wherever you are to the office to keep things secure.
It sounds simple, but this thing sells itself. A salesman who’s
often on the road gets his usual extension, voicemail, and presets
at the hotel and at the trade show without having to co-ordinate
anything with the hotel or trade show staff beyond an ethernet jack;
support people can work from home without having to route calls over
PSTN; people can switch desks inside the company and out to non-VPN’d
branch offices without rewiring or repatching; and all of this without
having to train the users anything beyond “plug in the cable”.
(On the office side you’ve got one of our ICPs (IP PBXes, if you like),
with a 6010 Teleworker Gateway between the ICP and the Internet; the
phone is programmed to talk to the 6010, which performs the necessary
magic to get it up and running. The 6010 is based on the 6000 Managed
Application Server, which used to be the e-smith server and gateway,
so the teleworker project was the one that kept my group around and
me in work.)
One interesting part is that I don’t think this would sell as software
or as a software and peripheral bundle; people don’t trust soft
phones yet, because they think that hardware shaped like a phone is
reliable and hardware shaped like a computer is not. “You plug in
your phone and it just works” is a much more impressive pitch than
“This software works from anywhere!”, even though the software is
easier to carry around.
The secret to practical VoIP is to make it act like it’s not VoIP at all.
