There is also an Ethernet/SIP overhead speaker. Voipsupply sells it.

 Quite surprising, yes! :-)
I am from north east Italy, now I live in Verona (Romeo and Juliet's city

I cannot do it connecting amp to the PBX. I have quite a long distance to
cover and a network is already there.
My phones are have a quite smart processor so we may probably run the
ices2 that you are suggesting or something similar.
I will check the links that you sent me.

Thanks,

Stefano Totaro,
 
Off topic.  I just noticed your name and was a little surprised!? ;-)
Are you in Italy / Sicily?
 
Anyways, you can achieve overhead paging through a sound card hooked to
an Amp and speakers from your PBX.  I have yet to do it but have read
about it.  I think this may be the better solution for you unless you
are set on doing it over IP.
 
Check here for several options
http://www.voip-info.org/wiki/view/Asterisk+Paging+and+Intercom
 
I am pretty sure if you use a ring group or meetme, there is no way
around each phone having it's own stream.
 
Interestingly, 3Com systems do conferencing and paging through multicast
which is a nice idea but in practice can be a real pain to configure
network components to work properly (especially if you do not control
the network or you are trying to implement paging between remote
offices).  I have spent hours on this exact problem in the past.
 
If it were me, I would probably not want all that traffic on the PBX
unless that is all that it will be doing or if you go the sound card
route.  I would use ices2 and let everyone stream from a different
server than the PBX.
 
Since you are using phones, I do not know that ices2 would work for you,
something must initiate the call.  I would probably have a second
Asterisk box to just handle the paging, setup an extension the dialplan
of the main PBX to dial the paging machine via SIP (and possibly include
Authenticate) that would drop the call into something like this:

 Yes, you are right we want to do VoIP telephone system capable also of

 So synchronization is a key issue if we want to avoid unpleasant effects.
 We are designing our phones and they will have also onboard amplifiers.
 What I am trying to understand is whether we may use the phone system
 also for this service or if it is better
 to go for a specific streaming technology (Ices2 is a good suggestion
 thanks).

 What happen if I put all the phones in a ring? Do they join the same
 multicast stream or a single stream for
 each phone will be created?

 Thanks again.

 Hi Guys,

 will repeat with loudspeakers in the same environment.
 I am a little concerned about synchronization of the phones and
 moreover it is not much clear to me if I have to open 50 connections

 Is there anybody that may give me some idea.

 I suppose you could do that although, I am unclear on the auto-answering
 softphone and the loudspeaker thing. Is this just for overhead paging
 or something?

 You could put all the phones in a ring group with ringall and use the
 computer's sound card to connect to an amplified speaker setup.

 You could also look at ices2 to stream audio or some other streaming
 technology.

 Thanks,
 Steve

I wouldn't do that with softphones, unless the softphones are designed
to do this.
The delay will vary depending on the audio card, OS, and drivers.

(And the phones might not all answer at the same time, but if you use
music on hold or so to play that should not be a problem).
