This is a crucial thing to keep in mind. I don't have all the answers,
but I have some. This won't clear the cloud of confusion much, but it
may clear a bit, and foster discussion.

Good question. But I agree with your point, until someone answers the
question, that it's $2.50/month and minutes.

Also known as ATA's or analogue telephone adapters. I, and others,
have a 3102, which gives me a POTS connector and an analogue phone
A not unreasonable device for providing flexibility through your
migration. vs. buying a dedicated pots, or dedicated ATA, device. For
example, suppose you buy the equivalent 2 ATA port device - you will
have to wire two current phones into this one device - what do you do,
put it in the wall between two offices? [Or, get a 4-port ATA and put
it in the middle of 4 desks.]
Picture it this way ... these devices would be used wherever in your
office you could currently take a phone from home and plug it in.
I expect you don't have many. Perhaps a few (e.g. fax lines, hot
phones). The rest will be DIGITAL sets. Probably Nortel digital sets -
the nortel is set up to understand their phones, and vice versa. You,
usually, could not take another manufacturer's phones and plug them in
to your nortel and have it all just work.

You don't want any at the moment. I can not stress this enough - you
MUST have a whole system replacement strategy in mind before you pay
your first $, or inevitably you will spend $ on the wrong things.
Doesn't mean this strategy isn't a gradual migration strategy, just
that you must know where you are, and where you want to get.
It's different in a home where you can create cut over and migratory
strategies that don't affect too many at once - and cell is usually a
I HIGHLY recommend you contact a consultant and work out a plan first.
Telephony is COMPLICATED. Be it analogue vs. digital sets vs fax lines
vs ground / loop start, centrex lines, and so on and so forth.
Further, probably, YOUR ENTIRE NETWORK STRUCTURE WILL CHANGE. Perhaps,
not by much, but you must know where you are and where you're going.
In essence, not infrequently, you end up with two completely
different, if not physically separate, networks. One for internet
(data), one for phones (voice). Typically they use different network
ips. It will not hurt you, and you probably should, start with your
internet gateway and work backwards, making sure you have QoS capable
equipment in place - gateway, routers, switches, and so on.
- an example of the complexity - are you prepared to re-wire every
room in your enterprise for a second network jack for the phone?
Probably not. Nor should you need to, practically. e.g. VoIP phones
not infrequently have two network jacks - one to the wall, one to the
computer. The computer now gets to the network via the network switch
in the phone.
This is non-trivial and bet your business (communications) stuff. Get
help. Considerable cost savings, yes, but a botched installation will
kill any chances of getting off of Bell. (User acceptance wise.)
The consultant should also be able to help you put together a master
plan, the cost savings resulting, and the timetable.

At the moment it's a non-issue - they won't be using their regular phones.

In the meantime, it's not all or nothing. Others will have additional
In the long term, voip phones will cost you less than buying an ATA
and using analog phones you don't have. (You may always need some Bell
lines, for faxing for example. This area is in flux, others will know
better. The last time I looked, the agreement you sign with Unlimitel
says you will not use it for faxing.)
- this biggest resistor to VoIP is REPLACING ALL YOUR CURRENT PHONES!
To that part of the end, start looking at replacing your faxing. e.g.
Multifunction devices can automatically route / e-mail at least one
destination / e-mail for all incoming faxes. This is the beginning of
migrating analogue fax to digital - when done you won't need faxing,
and thus you won't need the Bell line. IIRC Unlimitel offers a service
for faxing - redirect your fax number to them, kill your fax machine
and phone line in the process. You will incur that service charge, AND
the DID fee.
In the end, you are replacing the Nortel, perhaps gradually with a
parallel system. Perhaps, by parallel, more cost, but also more
certainty and assurance for those that control the budget.
- consider the case - what happens when the internet goes down. What
is your fallback strategy? One lone analogue phone line and phone? A
publicized cell number?
There is no reason you cannot use soft phones with your DIDs in the
meantime. Note that this TIES THE NUMBER TO A PHYSICAL 'OFFICE'. This
route, initially, will provide proof of concept for provider
(Unlimitel), your network, your computer (soft phone location), call
quality, and general concepts. [You may even decide to use softphones
only - if video calls become that sexy. Do all computers currently
A next step might be for some VoIP phones and or ATA's for analogue
phones you already have. This would allow you to move from the
softphones to hard phones. Cordless, for example, would gain you some
limited mobility. (Get 20' from physical office instead of having to
be in the office.) For that matter, so would a soft phone and
bluetooth headset. Or, get wi-fi VoIP phones instead - but you'll have
to implement a wi-fi infrastructure.
BEAR IN MIND - you won't be able to transfer calls, and use all the
other nifty features your current phones offer. (Because they allow
you to re-route calls WITHIN the nortel PBX. And because at that
moment you are on a soft phone that has no knowledge of the Nortel PBX.)
You can use call forwarding, but you will have to think through its
use carefully. e.g. to forward current extensions to soft phones, or
You can also use the opposite of ATA's (I don't know what they're
called), to convert an incoming VoIP line into a line the nortel
understands. You can then remove the bell line, and replace with the
line from this device. Note that, however, ultimately, this equipment
becomes a lost cost when you move to a full asterisk system. ATA's
have FXS ports, S = Station, and take analogue phones. ALA's (?) have
FXO ports, O = Office, and take analogue LINES. From Bell's
perspective, your location is an office. From your office's
perspective, the phone at your desk is a station.
Bear in mind, you probably have Centrex lines - which are not
analogue incoming lines. Moreover, you're probably getting a discount
for having multiple lines. As you migrate, you'll lose the discount.
You'll need to take this into account in you cost strategy.
You can also have a full-fledged asterisk system with hardware cards
that take in the Bell lines.
There are a lot of options, and telephony is complex. If not
technically, then in practical use. A not dissimilar way to think
about it, probably, is to think - what would it take to remove the
Bell lines and give everyone cell phones instead. No doubt you can
imagine the difficulties, both technically and user resistance wise.
For a small office with no key system or PBX, this is all much simpler
because they do far less complex things with their phones. As soon as
you have digital sets or a key / pbx system things rapidly get ...
Others will have better / more specific information than I. Hopefully
they will comment and, particularly, give you some local names that
can help you plan and navigate through this maze.
People stay with Bell because it's familiar, just works, and they have
other things to worry about. Not because it's cheap, or cheaper. The
costs are known and relatively small per month, versus a significant
chunk of change to just switch. Any any migration strategy will cost
the sum of both, plus some temporary equipment. Down the road you will
end up spending less per month, but it will be a multi-year payback
Get yourself sent on a course. Perhaps free / low cost training from a
vendor, such as Cisco.
Nothing I've said here is absolute. e.g. fax migration strategies. The
issues are known and vendors are always looking for better ways.
A consultant has value in that they can worry about the technical
complexity while you worry about user acceptance, and they know the
current market conditions - in the sense of the analogue and VoIP line
provider marketplace and conditions, area usual phone system use and
context, and current (VoIP) equipment availability and sources. They
will also help you cost justify things - by, for example, accounting
for the sale price of your old equipment, and bringing in the other
added value that implementing a wi-fi architecture may bring beyond
just phones. Such as reduced future wiring costs. Which may tie in
with PoE (Power Over Ethernet).
If you have a spare machine or a vm, it may well be worthwhile to just
jump into Asterisk with your DIDs and sofphones. There is a large
learning curve, regardless - you may want to skip the 'direct to soft
phone' aspects. Which is what I have / will do. I purchased a 3102
some time ago, then decided against the soft phone route, but haven't
yet implemented asterisk. [Recent loss of TV guide over analogue cable
is pushing me to make linuxmce, and therefore asterisk, a higher
Put another way ... you are changing basic, bet your business,
infrastructure here. How complex would it be to move everyone to PGP
in your organization? Or encrypt all your computer traffic internally.
