List,

I'm putting together a conf bridge solution and the main requirement is,

Must be scalable and out of the box be able to handle 1000 callers.

Any advice on hardware and necessary bandwidth?

Obviously looking to use asterisk but if there are better suited solutions it would be appreciated.

Thx,

- mike

Well, as far as Asterisk goes, you won't get 1000+ concurrent callers or
1000 MeetMe rooms on a single box. That is just not really possible,
especially given the intensity of the audio mixing required to make
MeetMe rooms happen. You would have to build your infrastructure in a
distributed manner; set up x amount of conferences on several machines
that are each only capable of having y users, and have a proxy or
something of the sort route the calls to the machines based on that
information. Or, have the conference rooms dynamically created
according to need in a load-balanced manner.

I suppose it is also possible to bridge two conference bridges together,
technically, by stimulating an Originate command that has a kickback to
a MeetMe() cross-connect on the near end and the far end. This would
theoretically allow you to have distributed conferences in which the
members are on multiple servers. But I haven't tested how well this
works / if it is desirable in any way whatsoever.

Commercial solutions - there are lots of them, but they are all rather
expensive if you wish to install them out of the box, and on-premises,
and are difficult to work with and customise. If all you need is a
conference bridge, you might want to consider purchasing it as a service
from someone who already provides it on a very large scale, such as
RainDance, etc., who I believe does it using TDM telephony gear.

Depending on your configuration, such as codec translation, TDM, etc
will determine the amount of servers required. I would think you
could probably get it done with three good servers doing strictly SIP
with same codec.
