As John points out, there is more than one way to skin these cats.

I pointed out how only marginally more complex it is to now introduce 
/ play with Asterisk (since most any lying around computer or vm would 
do you), instead of only just playing with soft phones / DID lines for 
the moment. [And Lori's presentation indicated how lifting the 
asterisk config files and dumping them on another box is all but 
trivial. Should you go to a different box, later. If OpenWRT can run a 
couple of VoIP lines, on what is essentially a P133 ...]

As John points out above, with a DID line and no asterisk, you have a 
1:1 DID line:person ratio. With asterisk you have 1:many.

Moreover, if you, even in your present situation, introduce Asterisk 
(receiving these DID lines) in front of and slightly to the side of 
your PBX, you can tie the two together, to some level of increasing 
co-operation, as a migration strategy. I suspect, ultimately, you 
could dumb down the PBX to the point of really just being a big switch 
wherein your current phones go straight through the PBX into Asterisk, 
for all call routing / handling features.

You're going to need the help of your pbx guy, regardless. And who 
knows, they may already know about 'this VoIP stuff.' Even if you make 
no purchases from them, they should be able to provide some level of 
support. Both from a 'what is this thing' perspective, and from a 
'where do we want to go, organizationally' perspective.

Take John up on this Paul. Even better if NetDirect has gone into this 
line of business. [DOH! I wasn't thinking of Asterisk / VoIP when I 
wrote that, I was thinking of PBX / Telephony / management / line of 
business.]

<sigh> John doesn't promote himself enough here (on this list):

http://www.netdirect.ca/solutions/fax.php - work towards getting off 
those very expensive fax lines. (Which wouldn't even involve VoIP, 
from your perspective. Your perspective, at this point, would be that 
of acquiring a fax solution - the underlying technology would be 
irrelevant.)

And to answer other recent threads on the list:

Linux laptops - http://www.netdirect.ca/products/ibm_notebooks.php


Anyways, back to this thread:
- you cannot do this on your own, you need help. Even if only for 
purchasing - ultimately, for your own sanity, you want a consistent 
end to end solution. I'm not suggesting vendor specific, but knowledge 
-person specific. That the pieces you purchase now work with the 
pieces you'll purchase next year, and how the disparate pieces hang 
together in a coherent, total, solution.
- you need a plan. Even if only staged. To avoid spending unnecessary 
$. And to determine what necessary, temporary, $, are required to keep 
everyone comfortable.
- you will need some outside, 3rd party, to bless the plan, before the 
budget controllers will approve the expenditure of the funds. Be it 
John, your PBX guy, or some cooperative combination of the two. Even 
if that cooperation is actually a migration.
