The first thing that comes to my mind is make sure that both offices
have the same ISP, or (this is a good guess) you are in trouble
with lag (or am I mistaken here?).

My venerable HP Scanjet 2100C died recently and I purchased an Epson
Perfection V350 Photo scanner.  Linux drivers were provided on their web
site (an associate company page) and when used in conjunction with
Kooka, works perfectly.  It was a lot easier to get going under Linux
than it was under Windows from memory.

Actually, out of curiosity, and since I want to get rid of Asterisk and
replace it with something (anything, so help me, anything at all) else.

FreeSWITCH is popular at the moment; the only other convincing option
I have run across is yate.

So, dear lazyweb, can you tell me:

Have you actually used FreeSWITCH or YATE in a small SIP-only environment?
Did it work well, reliably and with minimal maintenance?

Did it work effectively as an answering machine for home?
(That is, play a message, record the caller message, notify you,
 with nothing much more fancy than that available?)

Daniel

I put up my HP PSC 2410 (multi-function, including a scaner) on eBay
and got $5.50 for it (yes, five dollar fifty cents). Someone in
Melbourne who put up exactly the same printer at the same time got
same price (both of us didn't offer shipping so we didn't compete with
each other).

Might be worth a try.

No, but I can advise you how to answer that question for yourself:
http://www.sane-project.org/sane-supported-devices.html

See also the list of external providers; the HP software is referenced
from there, and supports more or less everything they do, but check
their HCL to be certain.

That is the software behind all the Linux scanning support, so what it
supports is what will work with Linux.

> New or second-hand is OK.

Then it becomes a question of finding something that meets your
technical requirements, is on the HCL, and is within your budget.

This is a good idea: Asterisk, and VoIP in general, have a non-trivial
number of potential issues that can cause you significant grief if you
don't know about them before you start.

This, or some other VoIP based solution, is a fairly reasonable strategy
though.  I would suggest you look into VoIP / Asterisk solution
providers in your area.

Re: [SLUG] Ask SLUG - IP Telephony

2009-02-09 Thread Marghanita da Cruz

Hi Ben,

I have done a variety of IT projects for a living in my time, including an
implementation of a proprietary VoIP system. While I arrived at the project with
good IT and Data Network experience and even some insight into Telephony and
long distance dedicated links - the main issue I struck was that the gulf
between the even Digital Telephony and Data worlds (both internal groups and
suppliers).

In no way is this  a definitive list - but things to watch out for include:
Network design,  Quality of Service (a big thing in Voice communication) and IP
telephony offers new features, sometimes at the cost of reliability of the good
old times when you could pick up a phone and expect it to dial and speak!

With regard to costing, the equipment is easy to cost, network/telephone budget,
the change/project management is usually more difficult. Testing, running
parallel systems and redirecting telephone numbers in different jurisdictions
isn't a trivial exercise either. Most  people now see mobile phones as the back
up system - which may need to be costed into the company if not the departments
bottom line.

I haven't used Asterisk - but it is worth checking out how it fits into a VoIP 
network, rather than just whether it handles Digital and Analog Phone lines/links.

the simple steps I did to get voip (not necessarily foss ) into the
places I manage

1) played with it a home - get to know your hardware/software/ acronyms
2) I went with a sipuria ata 3000 - if fits between you phone and the
exchange no need to change the phone or phone line - you do need an
internet service capable of handling voip.  Note I have also placed it
between a pabx and exchange.  sipuria got bought out by linksys now
cisco the current module is a spa3102.

The really good thing about them is once they are in place if anything
goes wrong, just pull the power and the fall back to straight through
connections to the pstn - as if the device wasn't there.

Now just route all your outgoing calls with a VSP. I would suggest
pennytel for one reason, they can make you number (CID) look like your pstn
number, my net phone can't so outgoing calls looks like they came from
your normal land line.

you will probably save most of your cost with the above setup.
(depending on the number of lines and simultaneous calls etc etc0

once you happy with this then maybe move forward with voip / ip handset

[SLUG] Installing a USB modem.

2009-02-09 Thread wbennett
Bought the Telstra USB modem.

Connected it to the laptop (Fujitsu, running Intrepid)

Nothing came up on the monitor.

Strange, I expected *something*, even if only an error message; but not
even that.

The light on the modem came on. But 0 else.

Is there something I should have done (connecting *after* booting up,
rather than *before*?)

Any help etc.
