Does anyone have any recommendations for MCUs? I started out looking at
the Cisco products, the IP/VC 3511 and modular IP/VC 3540 (as our
infrastructure is primarily Cisco), but I have since found that other
H.323 MCUs may offer greater functionality. Other suggestions are the
Codian 4200 MCU, Polycom MGC-25 and Tandberg MCU (which appears to
accommodate PRI ISDN for H.320 dial-in without a separate gateway).

The ability to dial-out to conference participants, a video-based
auto-attendant and the streaming of in-progress or recorded conferences
would be useful. The MCU needs to support H.263-only endpoints and both
continuous presence and voice-activated conferences.

Are there any comparative reviews of these vendors' MCUs?

Cheers,

Matt

Look at Radvision...

I would like more information about this

Each MCU of the market has its own pros and cons,
say price at least :-)
It is a matter of
- scale (how many parties, how much bandwidth, growing perspectives)
- connectivity (IP ISDN Voip 3G/UMTS
- features (splitscreen, data interaction/presentation, recording)
- administration (adhoc , participant driven, specialist driven, service
provider accounting)

Hidden quality factors like
- amount of interoperability problems with particular conferencing systems
- common protocol options (H.235,H.239,H.264,...)
are always work in progress and may decrease with newer releases
and increase with changes inthe endpoints

So I suggest to have a look on the conferencing systems involved too

Cisco is a OEM of Radvision

> Codian 4200 MCU,
Yes, nice for high performance IP-only self-running conferences
poor web interface, but this may change ...

Polycom MGC-25
> older stuff, there is a new series available

Tandberg MCU
(which appears to

you have to pay for a gateway anyway. Do you need ISDN ?
Tandberg and Polycom are expensive and build for service providers mainly.


> The ability to dial-out to conference participants,
This requires a appropriate scheduling/web interface,
Do you like to build a central service ?
Fixed group of targets or arbitrary future customers ?

a video-based

I suggest to have a look on DST media,
which is market leader in Asia (joined with Polycom last year)

DST`has a nice recorder unit offering playback on demand
As DST is the direct competitor of Codian,
I exspect Codian has a comparable solution :-)


Completing the list:
Radvision
VCON
Both come with a software-only client
VCON has the leading management system called MXM.
This offeres user driven telephony-like switching,
central management includes foreign endpoints too.
(Tandberg and Polycom do support their own endpoints mainly)

If you find a free comparison survey of MCUs, please let me know :-)
Paying for such infos is possible at http://www.wainhouse.com

Hope that helps
