I'm sorry if I did'nt put this message in the right group but then
again I couldn't really find out where to put it.
I've searched the seven seas for a product or solution to the problem
/ wish I have.

What I want to accomplish is the following:
We have a company with two sites, one in The Netherlands and one in
Belgium, they are all working with the same time registration system.
The clocks / time (on which they 'logon' and 'logoff' are synchronized
with the Dutch server.
But there's always a small time difference (few minutes) between the
Dutch server and the Belgium clock.
So people want to have there lunch break at 12 a clock (because the
radio says so) find out when they want to 'logoff' that the clock
shows 11.56

And now for the VOIP part:
I want to send (the same) audio signal: a bell, sirene whatsoever via
TCP/IP / our LAN 2 Lan connection to the Belgium Network, have an IP
Speaker on the other side wich I can connect to because it has a
Unique IP Adress.
This box has an audio out so I can connect a regular speaker to it.
This is what I had in mind but I didn't succeed in finding such a
solution on the net so I thought maybe VOIP can be a part of the
solution.
I saw the IP box on http://www.jetviewcam.com/
but I believe that's only for sending video / audo.

Hope you guys can be of any assistance...

Thanks in advance and happy easter!

Michael

Why not just fix the clocks? Sychronizing clocks on the server is free. If
you're talking about wall clocks, I've seen radio-synchronized clocks for as
little as US$10.

So why bother using VoIP when well-established standards like NTP (Network
Time Protocol) already exist? Use that, based on atom clocks, and not some
Rube Goldberg lash-up with audio.

THAT is a problem you should be able to fix, possibly by raising the
priority of the synchronization updates.

Could you Just hook up a phone with a Real Ringer and call the phone for
one,
two, or three rings?

I can't synchronize the clocks because we are talking about a
difference between an announcement / signal on a radio station and the
clock of the time registration system.
Over here (and I guess it happens all over the world) one station
starts the news at for instance 11.57 and the other at 12.05 depending
on how long the commercials take.
I just want to have the people have their lunch breaks when our time
registration server says so by giving a signal..
Thanks for your answer and time anyway Miguel.

Regards,

Mike

The point remains that it's a whole lot easier (and more accurate) to sync
clocks than to mess with audio transmission.

Set up one machine in location A, and one machine in location B. Spend 2
minutes configuring each one to sync its clock with an external NTP source.
Connect each one to a loudspeaker and program them to make a noise when it's
lunch time.

Presto, you have a much more reliable system (since the clocks will still be
more or less accurate even if the internet link is down at the moment when
lunch begins), and one that's almost infinitely easier to set up.

forget about voip for this problem. take any computer, sync its time via
ntp, attach a decent speaker and let it play an announcement (or make any
other noise for that purpose) at a defined time each day.

Thank you all for your replies but I guess I gave the wrong impression
that this post was about synchronizing the clocks. Wouldn't have
posted it in a VOIP group then.
I knew about ntp but we're talking about a Distribution Center in
Belgium and I don't a computer every 10 feet...
I want IP speaker boxes with there own IP address or something like
that so I can send one signal to all the boxes at a certain time...

http://www.control4.com/products/components/av.htm
has something like that but there has to be more...

Thanks again,

Mike

I think everyone understands the problem as you've described it, but we're
having a hard time believing that your proposed solution is anywhere near
the most efficient.

One computer somewhere in the nation of Belgium, and then wire that into a
PA system. The computer can be doing other things (print server, desktop,
whatever) at the same time.

Install a computer at each site and synchronize the time to the same NTP
server. Then hook up the audio out of the PC to your PA (intercom system).
Voila, both systems will now set off an alarm more or less simultaneously!

There's no need for your fancy audio over IP system.

So true, but if a man has a shiny new hammer all problems will look like
nails!-)

Here is a box that's specifically designed to send audio via IP:
http://voip.valcom.com/vip800.htm
A pair of these boxes can be used to extend a 600 Ohm paging port, but it
does not have to be paging equipment, a soundcard output will do just
fine.
Check it out, see if it would work for you.
