VOIP Conference

Hi,
I'm looking for a software useful to manage audio conferences (minimum 50
users).
I know that Skype allows a maximum of 4 users.
Do you know some other products which can be used for this purpose?
Many thanks.
Best,
Nic

You'd have to have some bandwidth for that many simultaneous calls. You
could install asterisk or Trixbox to do this.

Alternatively, I'm sure a voipfone virtual pbx ought to be able to do
this, at a cost. (99p per month per extension).......(does voipfone
offer conferencing?)

If your looking for a DIY approach then Asterisk itself can handle a
conference call that large. However, the real question is how do you
get the calls to the box.

VOIP -> Would need adequate Internet access
PSTN -> Would need lots of lines ;)

A hosted PBX service would solve the above issues and probably not cost
*that* much.

A solution that many small business's use is an access number that lets
you dial into a conference being held on the access numbers server.
This would be an 0845/0870 number.

Asterix can be used, but you're looking at a high-end server PC and
an Internet connection of at least 4Mb/sec bi-directional using g711
codecs. (so no home ADSL-MAX service here!) Obviously less if you are
willing to use something like the GSM codec.

And while that is not hard to provide, you're highly unlikely to
get it for free.

2 x ISDN 30's to start with, and if you use 0845/0870 type numbers,
then these can be used to help offset the cost of installation.

Or use a PSTN <-> VoIP carrier and have the calls delivered over a single
IAX trunk from the carrier to the Asterix server and back again. This
would be much more Internet bandwidth efficient than the same number of
incoming SIP calls, but it all depends on what the OP wants - if they
are looking for cheap conferencing from geographically distant locations
then this might not be suitable...

It all depends on the bandwidth usage. A lot of hosting companies offer
"Up to 100Mb" (or more) connections, but they are relying on the typical
bursty nature of web accesses, rather than the full-on streaming of a
PXB hosting a conference!

Or just use BT MeetMe ...

You could use easypabx. There is some question about the reliabulity,
in respect of down time, so you would have to take that into account,
but it is free and hosted on line.
www.easypabx.com
Alternatively, you could use the conference call faclity provided by
sipphone.com
You only need to include sipbroker in your dial plan (no registration
with Sipbroker is necessary as there is no username or password
required) and then dial
*747- 1 222 XXXXXXX
where XXXXXXX is any number you choose. This number can also be
accessed via a sipbroker PSTN access line. The number can be used
ad-hoc. However, if someone stumbles upon your conference number
(unlikely because there is often silence even on the 'party line'
number 0000000.) they would be able to listen in.

There are plenty of people listed at
http://www.voip-info.org/wiki/index....ited%20Kingdom
who can set up an asterisk system to do this for you.
